An engine working on otto cycle has a volume of 0.5 m^3 pressure 1 bar and temperature 27C at the commencement of compression stroke.At the end of compression stoke,the pressure is 10 bar. Heat added during the constant volume process is 200 kJ.Determine
Air standard efficiency
Mean effectine pressure
Ideal power developed by the engine if the engine runs at 400 r.p.m.so that there are 200 cycles per minute.
