A workpiece 2-in in diameter is to be machined on a lathe to 1.5-in in diameter. The total length of the workpiece is 3-in. It is recommended from handbook that a feed of 0.06 ipr, a cutting speed of 208 fpm, and a maximum depth of cut of 0.1-in be used. A 0.25-in overtravel should be used for cutter clearance. How long will it take to finish the part in minutes

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.
