Liquid water and water vapor (steam) are mixed in a mixing chamber to raise the temperature of water. the chamber has two inlets and a single exit and operates at steady state. the following data are provided at the two inlets and one exit. inlet-1 (state-1): p=500 kpa, t=30 deg-c, a = 0.01 m2, vel = 10 m/s, v=0.001004 m3/kg; inlet - 2: (state-2): water vapor at p =500 kpa, vel = 20 m/s, a = 0.1 m2, v = 0.376 m3/kg; exit (state-3): hot water at p= 500 kpa, v=0.0010 m3/kg, a = 0.01 m2

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.
