3. An ideal Diesel engine operates on 1 lb of air with a suction state at 14.1 psia and 100F. The pressure at the end of compression is 470psia and the cut -off is 6% of the stroke from head -end dead - center. Using air properties (r-53.34 ft-lbf/lbm-R, k=1.4, Cp=.24,Cv=.1714 Btu/lbm-R), determine compression ratio, percentage clearance, Qa, Qr, Thermal Efficiency, mean effective pressure.
