A fully developed turbulent flow of water at 20oC (density = 998 kg/m3 and viscosity = 1.002 x 10-3 kg/m. s) has an average velocity of 3 m/s at location 1. After flowing through the stainless-steel pipe with a diameter of D = 20 cm for a distance of 40 m, it undergoes sudden contraction to a diameter of d = 10 cm at location 2. 1 Determine the velocity at location 2. 2 Determine the total head loss between locations 1 and 2.

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.
