An ideal air standard heat engine cycle consists of the following processes: Air initially at 1.02 bar and 23oC is compressed isentropically to 21 bar; heated at constant pressure until the temperature is 940oC; expanded isetropically to its initial volume; finally cooled at constant volume to the initial pressure. Calculate the air standard thermal efficiency by determining the heat supplied and rejected. 2.
