In an air standard Diesel cycle, the compression ratio is 16, and at the beginning of isentropic compression, the temperature is 150C and the pressure is 0.1MPa. Heat is added until the temperature at the end of the constant pressure process is 14800C. Calculate the following.
(i) Cut off ratio,
(ii) Heat supplied per kg of air,
(iii) Cycle efficiency, and
(iv) Mean effective pressure of the cycle.
