Aspacer made of sae 1020 hot-rolled steel is in the form of a hollow cylinder with a nominal inside diameter of 3.2500 in and an outside diameter of 4.000 in. it is to be mounted on a solid steel shaft with a heavy force fit. specify the dimensions for the shaft and sleeve, and compute the stresses in the sleeve and shaft after installation at maximum interference. also determine the deformation of the sleeve and shaft. use the basic hole system. the modulus of elasticity of steel, e = 30 × 106 psi and poisson’s ratio, = 0.29.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
