Consider an ideal Brayton cycle executed between the pressure limits of 1,154 kPa and 100 kPa and temperature limits of 293 K and 1,047 K with air as the working fluid. Determine the turbine work output (kJ/kg) of the cycle (to the nearest unit value) using cold-air-standard assumptions.

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.
