A 200 g/l solution of common salt was discharged into a stream at a constant rateof 0.025 cms. Thebackground concentration of the salt in the stream water was found to be 10 ppm. At a downstreamsection where the solution was believed to have completely mixed, the salt concentration was found toreach an equilibrium value of 45 ppm. Required:
Estimate the discharge in stream

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.
