Aclean, 1 m2 , 15%-efficient module (stc), has its own 90%-efficient inverter. its noct is 45°c and its rated power degrades by 0.5%/°c above the 25°c stc. a. what is the stc rated power of the module? b. for a day with 6 kwh/m2 of insolation, find the kwh that it would deliver if it operates at its noct temperature. assume the only deratings are due to temperature and inverter efficiency.

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.
