A stationary diesel engine with a thermal efficiency of 40% produces 200 horsepower. The exhaust gas, which we suppose is air, has a velocity of 1400 R, whereas the intake has a velocity of 520 R. What is the mass flow rate if it accounts for half of the QL?

rate if it accounts for half of the QL?
30.13 Ib/s
14 kg/min
60.15 Ib/min
5.09 lb/hr
12.46 kg/s
15.3 Ib/min
NONE OF THE ABOVE
