Question

An air-standard Diesel cycle has a maximum temperature of 2000 K. At the beginning of compression, p1 = 95 kPa and T1 = 300 K. The mass of air is 12 g.

For a compression ratio of 20, determine:

(a) the net work of cycle in kJ

(b) the percent thermal efficiency.

Expert Solution
Step 1

Given:Maximum temperature in cycle, T3=2000 KAt the beginning of compression, P1=95 kPa, T1=300 KThe mass of air, m=12 g=0.012 kgCompression ratio, r=20Find:a the net work of cycle in kJb the percent thermal efficiency
