One and one-half pounds of water within a piston–cylinder assembly execute a carnot power cycle. during isothermal expansion, the water is heated at 500 f from saturated liquid to saturated vapor. the vapor then expands adiabatically to a temperature of 100 f and a quality of 70.38%.

(a) sketch the cycle on p–v coordinates.
(b) evaluate the heat transfer and work for each process, in btu.
(c) evaluate the thermal efficiency.

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

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

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.
