Problem 12.015 a mixture having a molar analysis of 66% n2, 17% co2, and 17% h2o enters a turbine at 1850°r, 8 atm, with a mass flow rate of 5 lb/s and expands isentropically to a pressure of 1 atm. the turbine operates at steady state and kinetic and potential energy effects can be ignored. (a) the temperature at the exit, in k. (b) the power developed by the turbine, in kw.

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.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.
