Three pumping wells along a straight line are spaced 200 m apart. what should be the steady state pumping rate from each well so that the drawdown in each well will not exceed 2 m? the transmissivity of the confined aquifer that all the wells penetrate fully is 2400 m2/day and all the wells are 40 cm in diameter. the thickness of the aquifer is 40 m and the radius of influence of each well is 800 m.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
