A 5-cm-diameter shaft rotates at 4500 rpm in a 15-cmlong, 8-cm-outer-diameter cast iron bearing (k 70 W/m K) with a uniform clearance of 0.6 mm filled with lubricating oil ( 0.03 N s/m2 and k 0.14 W/m K). The bearing is cooled externally by a liquid, and its outer surface is maintained at 40°C. Disregarding heat conduction through the shaft and assuming one-dimensional heat transfer, determine (a) the rate of heat transfer to the coolant, (b) the surface temperature of the shaft, and (c) the mechanical power wasted by the viscous dissipation in oil.
Water at 200KPa with a quality of 25%has it temperature raised to 20degrees celcius in a constant pressure process. What is the new quality and volume?
in a constant-pressure process steam at a 100 psia is presented to the piston of a pump and causes it to travel 3 in.
A manometer is used to measure the air pressure in a tank. The fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 28 in. If the local atmospheric pressure is 12.7 psia, determine the abs..
