The catalogue for a refrigerant 22, four-cylinder, hermetic compressor operating at 29 r/s. a condensing temperature of 40°c and an evaporating temperature of -4°c shows a refrigeration capacity of 115 kw. at this operating point, the motor (its efficiency is 90 percent) draws 34.5 kw. the bore of the cylinders is 87 mm and the piston stroke is 70 mm. the performance data are based on 8°c of sub-cooling of the liquid leaving the condenser. compute (a) the actual volumetric efficiency and (b) the compression efficiency.

Two microscope slides are placed horizontally, one on top of the other, with a drop of a dishwashing liquid between them. the gap between the slides is 1 mm. a machine pulls the top slide to the right with a velocity of 0.15 millimeters per second while the bottom slide is held stationary. a stress gage indicates that a shearing stress of 0.5 pa is required to pull the top slide with this velocity. if the dishwashing liquid adheres to both slides during this process, what is the viscosity of the liquid? specify whether your answer is dynamic or kinematic viscosity, and use appropriate units.

A8-in.-diameter steel shaft is to have a press fit with a 16-in-diameter cast iron hub. both the hub and the shaft are 10 in long. using maximum normal stress theorem and appropriate safety factor, it was identified that the maximum allowable circumferential (a.k.a. hoop or tangential) stress in the hub is to be 7.5 ksi. the moduli of elasticity are 30 x 106 psi for steel and 15 x 106 psi for cast iron. the poisson's ratio for both steel and cast ron is 0.3 and coefficient friction for the two materials is 0.12. determine a. the interference or the original mismatch, 8 b. the maximum axial force required to press the hub on the shaft
