Answer to Question #183629 in Mechanical Engineering for randz

Question

3. An ideal Diesel engine operates on 1.5 lb of air with a suction state at 14.1 psia and 100 o F. The

pressure at the end of compression is 475 psia 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.
