A stream of water vapor flowing at a rate of 250 mol/hr is brought from 600°C and 10 bar to 100°C & 1bar. PART A) Estimate the required cooling rate (kW) using the steam tables.

PART B) Estimate the required cooling rate (kW) using the CP of water vapor.

CP (water vapor) [kJ/mol°C] = 0.03346 + 6.88*10-6T

PART C) What is the physical significance of the difference between the values calculated in Parts A and B?

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 thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
