An iseal Brayton cycle has a pressure ratio of 6:1. The temperature of the air is 22 degrees celsius at the inlet to the compressor and 1080 derees celsius at the inlet to the turbine. Take specific heat at constant pressure and constant volume for air as 1,006 KJ/kg K and 0,717 KJ/kg K respectively. Calculate: 1. the compresion absolute temperature to one decimal place 2. the work ratio of the plant to three decimal places 3. the specific work output to the turbine and specific work input to the compressor , to one decimal place and SI unit 4. the thermal efficiency of the plant to one decimal place

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.
