MEASURING ATMOSPHERIC PRESSURE

The atmosphere is the densest at sea level. For measuring the atmospheric pressure a device, called a barometer, is used. There are in common use today two kinds of barometers — the mercury barometer and the aneroid barometer.

The mercury barometer was invented by the Italian physicist, Evan­gelista Torricelli, some 300 years ago. Standard atmospheric pressure is defined as the pressure equiva­lent to a column of mercury 76 cm high when the temperature is О Some barometers work on a different principle from the mercury “weather glass.” They are known as aneroid barometers. An aneroid barometer consists of a thin metal box from which the air has been re­moved. Some aneroid barometers are self-registering (they are called baro­graphs). Instead of a pointer a lever is moved.

Atmospheric pressure not only varies with altitude but also with time. Although the time variations are small and do not follow any regular law, they can be and are used by the weather bureau for pre­dicting weather conditions. When the barometric pressure begins to fall, it is a sign of changing weather. If the pressure goes on falling rain usually follows. As the storm passes, the barometer rises again. So, watching the changes of barometric pressure the weather for that place can be forecast.

If you look at the dial of a household barometer you can see the following readings: “Very dry, fair, rain, much rain, change, stormy.”

CENTRIFUGAL PUMPS

Centrifugal pumps comprise a class of pumping machin­ery in which pumping of liquids or generation of head is effected by rotary motion of one or more impellers. The great variety of centrifugal pumps may be reduced to a few fundamental types.

Every pump consists of three principal parts: an impeller which forces the liquid into a rotary motion; the pump casing which directs the liquid to the impeller and leads it under a higher pressure; and a drive to put the impeller into rotary motion.

Upper limits of capacity produced by centrifugal pumps are constantly increasing. Pressures as high as 5,400 psi are being produced by centrifugal pumps (three in series) for operation of hydraulic presses.

The largest pump delivers 607,000 gpm against 310-ft head, driven by 65,000-hp motors at 200 rpm. In small sizes, centrifugal pumps are produced in millions of units a year for domestic water supply, and industrial use.

2. Draw the picture of centrifugal pump. What parts do you draw? Say them in English. (Нарисуйте схему центрифуги. Какие части вы нарисовали? Назовите их по-английски).

3. Answer the questions (ответьте на вопросы): 1.What chemical equipment do you know? 2. What is the purpose of that equipment? 3. What main classes of the equipment do you know?
