Heat Engine

Heat Engine : (Power Plant of an Automobile)  A device which is used to convert one form of energy into mechanical energy is called an Engine . The heat energy produced by burning of the fuel is converted into mechanical power, then it is called a Heat Engine.  Heat engines are classified into two types.  1.External Combustion Engine  2.Internal Combustion Engine  1. External Combustion Engine  An external combustion engine is a Heat engine where a working fluid, is heated by combustion in an external source like Boiler. The fluid then, by expanding and acting on the mechanism of the engine, produces motion and usable work. The combustion process takes place outside the mechanical engine system.   Eg. Steam Engines, Ancient Marine Engines  2.Internal Combustion Engine  An internal combustion engine (ICE) is a Heat engine where the combustion of a fuel and air occurs inside the engine combustion chamber that is an integral part of an engine....

Fluid Mechanics

Differential Manometer 1.Introduction Differential manometers are used to measure the difference of pressures between two points in a pipe or in two different pipes. There are two types of differential manometers.             1.   U-tube upright differential manometer             2.   U-tube inverted differential manometer 1.2  U-tube Upright Differential Manometer It is used to measure pressure difference at two points in a pipe or between two pipes at different levels. Case 1 - U-tube upright differential manometer connected at two points in a pipe at same level The construction and arrangement of a manometer connected at two different points, A and B, of a pipe is shown in figure 1                              Fig.1U-tube upright differential manometer    Let,          ρ 1  = densit...
