The annual storage in broad river watershed is 0 cm/y. annual precipitation is 100 cm/y and evapotranspiration is 50 cm/y. the sandy loam soil in the watershed has an infiltration rate of 5 × 10-7 cm/s. the area of the watershed is 40 km2. calculate the annual flow at the outlet of broad river. what is the runoff coefficient for this watershed?

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.
