A steady-flow Carnot cycle uses water as the workingfluid. Water changes from saturated liquid to saturated vaporas heat is transferred to it from a source at 250C. Heat rejectiontakes place at a pressure of 20 kPa. Show the cycle ona T-s diagram relative to the saturation lines, and determine(a) the thermal efficiency, (b) the amount of heat rejected,and (c) the net work output.

IC engines

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.
