The most common type of pump used in the process industries is the cugalentrif pump . In such a pump,a rotating wheel (or disk ) with vanes on it,called an impeller , is used to impart energy to the liquid .

Many compression problems involve conditions beyond the practical capability of a single compression stage . Too great a compression ratio may cause excessive discharege temperature or other design problems .
Every compressor is made up of one or more basic elements . A single element ,or a group of elements in parallel , comprises a single-stage compressor .
Four methods are used to compress gas . Two are in the intermittent class, and two in the continuous flow class .( The are descriptive ,not thermodynamic or duty classification terms .) These methods are to
Compression of gas has one basic goal-ti deliver gas at a pressure higher than that originally existing. The original pressure level may vary from low absolute pressures (fractions of
There are three fundamental types of heat transfer: conduction ,conwection and radiation.All three types of heat transer may occur at the same ,and it is advisable to consider the heat transfer by each type in any particular case.
If a material is to be cooled,a shell-and-tube heat eexchanger can also be used. The cooling medium is normally water, or cold brine. Brine (a solution of salt in water) is used
