An eight-cylinder, four-stroke Otto cycle runs at 5000 rpm. The compression ratio is 12.2, and the engine displacement is 396 in3 . Air enters the engine at 14.4 psia, 70 o F. The maximum temperature in the engine is 4000 o F. Using an air-standard analysis, determine:
a. The net work per cycle per cylinder (in Btu).
b. The cycle thermal efficiency.
c. The net power output (in kW and hp).
d. The airflow through the engine (in ft^3/min).

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
