4. The maximum dry density of a proposed borrow soil was found to be 2.2 Mg/m3, and the optimum water content was 13%. The borrow soil has a natural water content of 10%, a degree of saturation of 50%, and a specific gravity of solids of 2.63. Specifications require the borrow soil to be compacted to 95% of the maximum dry density.(a) How many cubic meters of borrow soil will be required to make one cubic meter of compacted fill at the specified dry density?

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.
