Given that there are approximately 12 no. 1 1/4 inch (internal diameter) steel pipes; a) Determine the effective length of the pipes to the wet areas given that the required pressure is 39.24kPa at a discharge flow rate of 0.001 m/s.

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.
