Steam enters a turbine at a pressure of 6 mpa and temperature of 500°c with a flow rate of 140,000 kg/hr, and leaves as saturated vapor at 40 kpa. the turbine generates 4000 kw of power and is contained within a room at a temperature of 25°c. -draw an appropriately labeled diagram -list assumptions, and derive a variables-only equation for the entropy generated during this process in terms of intensive properties and known variables. -determine the entropy generated through the turbine.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

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.
