Q$5(5$ m$)$:

The formula $Q=t^2$ is used to calculate the power of a fire $($also called the

heat release rate$).$ In the formula:

$Q=$ Heat$-$Release$-$rate in kW

$=$ Fire growth coefficient in $k\frac{W}{s^2}$ and

$t=$ the time after ignition in s $.$

Calculate the Heat$-$release$-$rate of a fire involving corrugated cardboard having a

Fire growth coefficient of $0\mathrm{.}01127k\frac{W}{s^2},$ after $0\mathrm{.}2$ hours of burning.
