Answer all the questions in the spaces provided.

(a)

(i)

Define pressure.

(ii)

Show that the SI base units of pressure are $\text{kg m}^{-1}\ \text{s}^{-2}$ .

(b)

Gas flows through the narrow end (nozzle) of a pipe. Under certain conditions, the mass $m$ of gas that flows through the nozzle in a short time $t$ is given by

\frac{m}{t} = kC \sqrt{\rho P}

where $k$ is a constant with no units,
$C$ is a quantity that depends on the nozzle size,
$\rho$ is the density of the gas arriving at the nozzle,
$P$ is the pressure of the gas arriving at the nozzle.

Determine the base units of $C$ .
