As the cold water is discharged from this tube into the bottom of the tank, it is heated by electric elements or a gas burner. Hot water, being lighter in weight than eold water, rises to the top of the tank where it is drawn off through an outlet tube to faucets and appliances that use hot water.
Whether water is heated by electricity or gas, the temperature of the water is controlled by a thermostat that "senses" temperature. As water heat reaches a preset temperature, the thermostat responds by closing the switch that allows the electric current to flow. When water falls below the preset temperature, the heating elements are turned back on.
About Electrically Operated Units
Two types of electrically-operated, water heaters prevail: induction and immersion.
As the term indicates, an induction type heats water by inducting heat from an electric coil. The electric coil does not come into contact with the water. Instead, the element is strapped around the outside of the tank and is covered with heavy insulation, causing heat to pass through the wall of the tank.
In contrast, an immersion water heater has the elements in direct contact with water. Elements pass right through the wall of the tank, with openings around them sealed tightly so the tank maintains its watertight integrity.
How Gas Operated Units Work
Water heaters that use gas as the heating element have as their main parts a gas burner and pilot light. The burner is positioned outside the tank — never in contact with water. Its flame is directed against the bottom of the tank so cold water being discharged from the dip tube is heated.
Water Heaters
Situated in such a position as to be kept hot at all times by the pilot light is a flame sensor. If for some reason the pilot light goes out, the flame sensor cools, and in so doing cuts off the flow of gas to theburner.
Selecting a Water Heater
If you are building a new home, remodeling an older home, or replacing a water heater that has failed, you will want to select a new heater that best meets your family's needs. The General Public Utilities Corporation has provided a guide that may be used to make a selection:
This article is mostly likely taken out of______.
A.a textbook intended for technicians
B.a consumer guide
C.a book on the history of electric appliances
D.an operation manual for a type of water heater

The Development of the Modern Hot Air Balloon
The modern hot air balloon is constructed by suspending a wicker basket underneath a large bag of nylon fabric, known as an envelope. The wicker basket carries the balloon's pilot, any other passengers, and the propane tanks that provide the balloon with a source of fuel The propane tanks are connected by hose to a pair of burners, which are Located between the basket and the envelope. When the burners ignite, their heat passes through the balloon's skirt—a circular sheath of fire-resistant material at the mouth of the envelope—and finally into the envelope itself. Located at the top of the envelope is a parachute vent, a mechanism that allows the pilot to release hot air and increase the balloon's rate of descent when required. This is controlled by a parachute valve cord that extends through the balloon, and into the basket.
The use of hot air balloons can be traced back to the Three Kingdoms era of Chinese history (220-280 AD). Huge Lang used these early incarnations, known as Congaing lanterns, as military signals. The first manned flight on record took place in France on October 15th, 1783. In a balloon constructed by Jacques-Etienne Mongolia, a Frenchman named Pitter de Rosier was elevated eighty feet off the ground. Modern hot air balloons, with their capacity to ascend or descend and occasionally 'steer' at the pilot's will, were first developed by Ed Yost in the 1950s. The Bristol Belle is generally regarded as the first modern hot air balloon, and had its inaugural flight in 1967. Since then, balloon technology has become extremely sophisticated. Some hot air balloons have reached altitudes of 21,000 meters, traveled over 7,500 kilometers, and reached speeds of up to 400 kilometers per hour.
Hot-air balloonin8 is generally a safe activity, and serious accidents are rare. In the event that something does 8o wrong, several items of safety gear are useful to have on board. In case the pi to light and the auxiliary pies ignition fail, it is a good idea to have a welding torch flint sparker available for the pilot's use. Given the propane combustion used to propel the hot air balloon, a fire extinguisher is an absolute necessity. Flame-resistant gauntlets made out of either leather or name are required for the pilot so that a gas valve can be disabled even if an open flame is present. While name is a specially-manufactured synthetic form. of fire-retardant material, synthetic clothing is generally a hindrance to fire safety, and clothing made of natural fiber is a superior option for pilots. Final[y, a handling line—a long rope that can be thrown overboard—is a vital precautionary measure that allows people on the ground to steer the balloon away from trouble.
To ensure baton longevity and safety in operation, it is vital that hot air batowns be maintained and repaired while not in use. Keeping the envelope dean and dehumidified is an important step that prevents mould from forming on the fabric. This is especial[y important if the balloon has landed in a wet or muddy environment. The burner and rue[ system also requires regular maintenance. This can involve the replacement or repair of damaged hoses and any sticking or leaky valves. The wicker basket has skids on its bottom to help it gain traction upon landing; over time these are worn down, and will need to be replaced. International regutations stipulate that balloons must be given a full inspection every one hundred flight hours, or twelve months. This ensures that any problems can be rectified before they become hazardous.

Caught in the spotlight of hostile scrutiny, global companies from the Gap to McDonald's to Wal-Mart have launched so-called social-compliance programs to fend off critics of their supply chain practices. These new programs frequently require company suppliers to meet basic labor-practice standards. That compliance is all excellent first step, but it requires strategic thinking, not just-in-time tactical responses.
Starbucks has charted a course that suggests a new strategic template, one that other brand-driven multinationals might want to explore. When anti-globalization activists singled out Starbucks for having exploited third-world farmers, the company saw the attack as a direct threat to the brand and to its public commitments to social responsibility. But rather than assume a purely defensive posture, Starbucks launched a pilot program to fundamentally change its relationship with its suppliers. The company began to actively cultivate and reward environmentally and socially responsible suppliers a strategic gamble it calls sustainable sourcing. Not only could sustainable sourcing defend against Starbucks's critics, company executives reasoned, but it could build the brand and even drive the company's growth. This spring, Starbucks announced that it was making sustainable sourcing a cornerstone of its global strategy.
With annual growth in the late 1990s at about 20%, Starbucks executives were confident the demand was them to sustain this rate of growth. But they knew their supply chain's future was less predictable and reliable. If the flow of specialty beans from around the globe fell short, both its growth plans and the quality of its coffee would be at risk.
To protect its coffee supply, Starbucks realized it had to identify and nurture partners that could meet its quality standards and keep pace with its increasing demand. Moreover, to protect its brand, the company had to be certain that these suppliers shared its commitment to corporate citizenship. In 2001, the company launched a pilot called the preferred supplier program to attract and reward farmers committed to socially and environmentally responsible farming. The company reasoned that the farms that took the best care of their employees and land would be the most sophisticated, responsive, and responsible suppliers just the sort to help Starbucks fulfill its aggressive growth plan.
To become a preferred supplier, farmers must apply to the program. Reviewers evaluate applicants on 20 measures to determine how well they adhere to sustainable environmental practices (procedures that protect the scarce real estate on which high-quality coffee can grow ) and responsible social practices (methods, for example, that reduce the risk that deliveries will be compromised by labor unrest, corruption, or legal violations ). Suppliers accepted into the program are awarded points for meeting environmental, social, and economic criteria; the more points they earn, the more Starbucks pays them for their coffee. Preferred providers will typically receive a 5% premium on each pound of beans they sell. They can also win long-term contracts to reduce market risk and receive credit to fund improvements that promote sustainability. With the recent expansion of the pilot program to all of its supply chain, Starbucks expects that in five years 60% of its coffee will come from preferred suppliers.
Starbucks's idea is innovative and refreshingly proactive. But it's clearly a gamble. It's uncertain whether sourcing this way will pay off, either by satisfying the company's critics or by assuring adequate supplies. While the jury's still out, brand-driven companies may want to try this e
A.They are being criticized for what they have done.
B.The programs are part of their long-term strategy.
C.They want to be operating in accordance with relevant standards.
D.Their supply chain practices have lagged behind modem development.
