I need solving question 2 only?

Q1.

In an Otto cycle air is compressed from an initialpressure 120 kPa and temperature 350 (K). The cycle has compressionratio of 10. In the constant volume heat addition process 1000kJ/kg heat is added into the air. Considering variation on thespecific heat of air with temperature, determine,

(a) the pressure and temperature at the end of heataddition process (show the points on P-v diagram)

(b) the network output

(c) the thermal efficiency

(d) the mean effective pressure for thecycle

The gas constant of air is R = 0.287kJ/kg.K

Q2.

Repeat Q1 using cold air standardassumption.

(Properties: The properties of air at room temperatureare cp = 1.005 kJ/kg·K, cv = 0.718 kJ/kg·K, R = 0.287 kJ/kg·K, andk = 1.4)
