Acrew capsule has re-entered earths atmosphere and slowed to a speed of v=1134 m/s at an altitude where the static temperature is t=200 k and the static pressure is p=1kpa what is the total temperature experienced by the capsule? assume the air behaves as a calorically perfect gas with ratio of specific heats y=1.4 and gas constant r=287 j/kg/k.

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.
