3. Water is the working fluid in a Rankine cycle. Superheated vapor enters the turbine at 10 MPa, 480 C, and the condenser pressure is 6 kPa. The turbine and pump have isentropic efficiencies of 80% and 70% respectively. Determine for the cycle (a) the heat transfer to the working fluid passing through the steam generator in kJ/kg, (b) the thermal efficiency, and (c) The heat transfer from the working fluid passing through the condenser to the cooling water in kJ/kg

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.
