In a venturi nozzle flow, the inlet conditions are p1 = 08 x 103 kPa gauge and d1 = 100 mm and the outlet conditions are p2 = 0 kPa gauge and d2 = 50 mm. Find the flow rate of water. Assume CD = 0.98 for the venturi coefficient. a) (30) Neglect viscous effects (friction loss).
b) (10) Consider viscous effects.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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.
