A well 300 ft deep is proposed in an aquifer having transmissibility of 12000 gpd per foot width of aquifer and a coefficient of storage of 0.006. The static water level is expected to be 100 feet below the ground surface, the well is pumped at 600 gpm and the well diameter is to be 12 inches. What will be the pumping lift from the well at the end of 2 years

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
