Q1Physical Quantities and UnitsFree sample

Answer all the questions in the spaces provided.

(a)

(i)

State the SI base units of volume.

base units of volume = ______

(ii)

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

(b)

The volume $V$ of liquid that flows through a pipe in time $t$ is given by the equation

\frac{V}{t} = \frac{\pi P r^4}{8 C l}

where $P$ is the pressure difference between the ends of the pipe of radius $r$ and length $l$ . The constant $C$ depends on the frictional effects of the liquid.

Determine the base units of $C$ .

base units of $C$ = ______
