Introduction: We all know that the engine develops power by burning an air-fuel mixture & hence to increase the power output the more fuel has to be combusted in each cycle of engine operation & since the engine burns the specific air-fuel ratio more air has to be added when you want to add more fuel. At a normal…

Introduction: The hydraulic machine which converts mechanical energy into hydraulic energy is called a pump. The hydraulic energy is basically in the form of pressure energy. If the mechanical energy is converted into pressure energy, by means of centrifugal force acting on the fluid, the hydraulic machine is called a…
