Air flows through a device such that the stagnation pressure is 0.4 mpa, the stagnation temperature is 400°c, and the velocity is 528 m/s. determine the static pressure and temperature of the air at this state. the properties of air at an anticipated average temperature of 600 k are cp = 1.051 kj/kg·k and k = 1.376.

What precautions should you take to prevent injuries when dealing with heavy loads?

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

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.
