A diesel engine (also known as a compression-ignition engine and sometimes capitalized as Diesel engine) is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel‚ which is injected into the combustion chamber. This is in contrast to spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline)‚ which uses a spark plug to ignite an air-fuel mixture. The engine was developed by Rudolf Diesel

• Pressure at the bottom of a column of air reaching to the top of the atmosphere is the same as the pressure at the bottom of a column of water 10.3 m high. • Consequence: The highest the atmosphere can push water up into a vacuum pump is 10.3 m. • Mechanical pumps that don’t depend on atmospheric pressure don’t have the 10.3-m limit. © 2010 Pearson Education‚ Inc.

Centrifugal Tutorial Centrifugal Pump A centrifugal pump is one of the simplest pieces of equipment. Its purpose is to convert energy of an electric motor or engine into velocity or kinetic energy and then into pressure of a fluid that is being pumped. The energy changes occur into two main parts of the pump‚ the impeller and the volute. The impeller is the rotating part that converts driver energy into the kinetic energy. The volute is the stationary part that converts the kinetic energy into

pointing toward a piston that is free to move‚ and is sometimes connected to a rod. When the force is applied‚ the piston moves up or down. The equations are: equations Of course‚ as Prof. Newman says‚ "there is no free lunch‚" In order to move the larger area‚ the smaller area has to move a lot in order to move the larger area a little. The larger area is nine times greater than the smaller area. In order to move the larger piston one inch‚ the smaller piston has to move nine inches
