26 Training activity on using variable specific heat method

Air (ideal gas ) undergoes a polytropic (n = 1.3) compression in a piston–cylinder assembly from p1 = 1 bar, T1 = 22 C to p2 = 5 bar. Employing variable specific heat assumption, determine the work per unit mass, in kJ/kg, heat transfer per unit mass, in kJ/kg,
