Heat transfer: In a triple effect evaporator, the heat transfer for an evaporator is calculated as q = UA (TI - TF) where TI is the initial temperature, TF is the final temperature; U and A are constants. Given that heat transfer for the first evaporator : q(1) = UA (TI - TB); second evaporator : q(2) = UA (TB - TC); third evaporator : q(3) = UA (TC - TF) where q(x) is the heat transfer function, TB is the temperature of second inlet and TC is the temperature of third inlet, prove that the overall heat transfer Q = q(1) q(2) q(3) = UA (TI - TF).

HEAT TRANSFER - ANSWER 5.1 : Q = q(1) + q(2) + q(3) = [ UA (TI - TB) ] + [ UA (TB - TC) ] + [ UA (TC - TF) ] = UATI + (UATB - UATB) + (UATC - UATC) - UATF = UATI - UATF = UA (TI - TF) (Proven).
