Drawdown at 0.2 m diameter, fully penetrating well, which has been pumping at the rate of 1,000 m3 /d and reached a steady-state, is determined to be 0.7 m. The aquifer is unconfined and 10 m thick. An observation well 10 m away has a drawdown of 0.2 m. a) Determine the hydraulic conductivity of the aquifer. b) How far from the pumping well does the cone of depression extends

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
