Q-3: The air enters the compressor of an open cycle gas turbine at 1 bar and 20°C. The overall pressure ratio of the cycle is 4/1. The isentropic efficiencies of the compressor and turbine are 80% and 85% respectively. The air/fuel ratio used is 80/1 with a heating value of 41800 kJ/kg. The pressure drop in the combustion chamber is 0.11 bar and the combustion efficiency is 96%. The air flow rate is estimated to be 5 kg/s. Determine: • Power output in kW. • Cycle thermal efficiency. Assume that the working fluid around the cycle has the properties C, 1.10 kJ/kg K and y= 14

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.
