Awell is producing from a confined aquifer under steady state condition. an observation well 100ft from the pumping well shows a drawdown of 5 ft, while an observation well 20ft from the pumping well shows a drawdown of 16ft. what is the drawdown at the pumping well of radius 8 inches? if the well produces 20ft3/min, what is the transmissivity of the aquifer?

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.
