Consider the purely subsonic flow in a convergent-divergent duct. The inlet. throat, and exit area are 1 m', 0.7 ni', and 0.85 m', respectively. If the inlet Mach number and pressure are 0.3 and 0.8 x lo5 ~/m', respectively, calculate: a. M and p at the throat b. M and p at the exit

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.
