A 12 inch diameter well in installed in an unconfined aquifer with a saturated thickness of 39.4 ft and a hydraulic conductivity of 131.2 ft/day. The radius of influence of the well is 6,560 ft. Determine the drawdown at the well and at 98.4 ft from the well for a steady-state discharge of 300 gpm.

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?
