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.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
