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.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
