A part at Belleh Fontem Manufacturing requires holes of the size 0.50plus or minus0.01 inches. The drill bit has a stated size of 0.50plus or minus0.005 inches and wears at the rate of 0.00017 inches per hole drilled. Give the most and least number of holes that can be drilled with one drill bit before it has to be replaced.

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.
