The radiant energy incident on the earth's surface on a sunny day is roughly 9 0 0 W m 3 If a house is designed

The radiant energy incident on the earth's surface on a sunny day is roughly 900Wm3 If a house is designed that will have a circulating forced air central heating unit, and solar energy is contemplated as a heat source and backed up with a conventional electric heater. If air is to be fed at a rate of 750mmin at 25C and 1atm, and the air is to be heated 1055C before being discharged into the living space, and solar collector plates of dimensions L=40m,W=30m are used. Assume 30% of the radiant energy incident on the plates is used to heat the air. Calculate the REAT rate should be provided by the supplementary heater? )=8.314(Pa),m3mol.K,Cp(air)=1.005kJkgK,1(atm)=(1.015**105(Pa).
