Question

The rate of heat loss Q_loss through a window or wall is a
the function of the temperature difference between inside
and outside ∆ T , the window surface area A , and the R
value of the window, which has units of (ft² .h . ° F)/ Btu.
( a ) Using the Buckingham Pi Theorem, find an expression
for the rate of heat loss as a function of the other three
parameters in the problem. ( b ) If the temperature
difference ∆ T doubles, by what factor does the rate of
heat loss increase?
