Question A tire pump has piston whose cross-section area is 0.001 m2. If a force of 150 N is applied to the pump, find the pressure on air in the pump. P = F/A

Solution Pressure $p$ and force $F$ are related as

$$p = \frac {F}{A}$$

where $A$ is cross-section area. Hence

$$p = \frac {150\,N}{0.001} = 150000\,Pa$$
