Gyou are cold drawing a steel wire from 2 mm to 1.8 mm with a carbide die. the pulling velocity is 0.75 m/s. the coefficient () is 0.12. the die angle () is 4 degrees. for steel, k = 695 mpa and n = 0.32. there is no back stress in this process. a) determine if this draw is possible. b) determine the pulling force. c) determine the power.

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.
