A two-cylinder 250 cm^3 displacement motorcycle engine that operates on an ideal Otto cycle at 4500 RPM. The compression ratio is 9. Air enters the engine at 100 kPA, 27 degree C and peak temperature is 2250 degree K. Determine:
a. the net work percylinder
b. the cycle thermal efficiency
c. the net power output
d. what is the cycle efficiency if a cold-air-standard analysis is used with the following values: R = 8.314 kJ/kmol-K, cp = 1007 j/kg-K, cv = 0.720 kj/kg-K?
Cortical bone gets weaker with aging, but it turns out that diaphyseal diameters can also change with aging, particularly in males, such that the safety factor of the diaphysis is approximately constant with aging.
