A contractor is trying to estimate the distance to be expected of a draw-down of 4.81 m from a pumping well under the following conditions:Pumping rate 0.0280 m3/sPumping time 5 1,066 dDrawdown in observation well 5 9.52 mObservation well is located 10.00 m from the pumping wellAquifer material 5 medium sandAquifer thickness 5 14.05 mAssume that the well is fully penetrating in an unconfined aquifer. Report your answer to two decimal places.

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.
