At the beginning of the compression process of an air-standard Diesel cycle, p₁ = 95 kPa and T1 = 300 K. The maximum temperature is 1800 K and the mass of air is 12 g. For compression ratios of 15, 18, and 21, determine,
(a) the net work developed, in kl,
(b) the thermal efficiency
(c) the mean effective pressure, in kPa.
