2. An engine operating on the air standard heat engine has a compression ratio of 18. If the maximum cycle pressure at Isobaric heat addition is 55 bar, maximum and minimum cycle temperatures are 1893 K and 48°C, respectively. Determine • The amount of heat absorbed • The amount of heat rejected • The efficiency of the cycle • The mean effective pressure
