A community is installing a new well in a regionally confined aquifer with a transmissivity of 1589 ft^2/d and a storatitvity of 0.00005. The planned pumping rate is 325 gal/min. There are several nearby wells tapping the same aquifer, and the project manager needs to know if the new well will cause significant interference with these wells. Required:
Compute the theoretical drawdown (h0-h) caused by the new well after 30 days (t) of continuous pumping at the following distances

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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
