An air standard dual cycle has a compression ratio of 14 and a cutoff ratio of 12 the pressure ratio during the constant-volume heat addition process is 15 dotormine a) the specific volume of the air at the start and end of the compression, b) the maximum gas pressure and temperature when this cycle is operated at 80 kpa and 20°c at the beginning of the compression. c) the amount of heat added, d) the thermal efficiency use constant specific heats at room temperature

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.
