Consider an air-standard Diesel cycle. At the beginning of compression, pressure & temperature are 95kPa & 300 K, respectively. Assuming mass of air to be 12 g, with maximum cycle temperature of 1800 K and compression ratio of 15, determine: (a) Net-work of the cycle (kJ) (b) Mean effective pressure (kPa) (c) Thermal efficiency

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.
