Steam enters an adiabatic convergent-divergent nozzle at 0.6 MPa, 200 o C, with a velocity of 50 m/s. It expands to a pressure of 0.13 MPa to increase its velocity of 600 m/s. Determine the final temperature if the steam is superheated in the final state, and its quality if it is in the wet region.

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.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
