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.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
