The following expression is known as Newton's Law of cooling and is used to

calculate the rate of heat transfer $(Q)$ caused by a temperature difference $(T).A$ is

the surface area through which the heat is transferred, and $h$ is the heat transfer

coefficient.

$Q=T*A*h$

Calculate the heat transfer $(Q)$ in $k\frac{J}{s}$ for the following conditions:

$h=2000\frac{\text{B}\text{t}\text{u}}{f{t}^2*h*F},A=300m^2,T=30K$
