At the beginning of the compression stroke, the volume of a certain diesel engine cylin-der is 1.000 liter and it is filled with air at 300 K and 100 kPa absolute. At the end of the compression stroke the air is at 800 K and 4280 kPa absolute. What is the work done by the piston on the air during the compression stroke?
Horsepower and efficiency of three-phase motor, If a fully loaded 440V, three-phase motor draws 12.4 A at 86% power factor (pf). It's speed is 1730 rpm and its torque output to a mechanical load is 29.1 lb-ft x 1.356 = 39.5 Nm.
The desire is to raise the temperature of the ambient air from 60 degree F to 350 degrees F ---- I need to calculate the amount of steam energy in BTU's per minutes and lbs of steam per minute necessary to accomplish the increase in air temperatur..
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.
