The storativity of a confined aquifer is found to be 1.8 x 10-4 as a result of a pumping test. The thickness of the aquifer is 50m and the porosity of the aquifer is 0.25. Determine the fractions of the expansibility of the water and the compressibility of the aquifer skeleton in making up the storativity of the aquifer. Assuming water is at 15ºC. The compressibility of water is 4.673x10-10 m2/N.

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.
