Given:
- gauge pressure of bicycle tyre,

- length of cylinder of the pump,

- area of the the cylinder of the pump,

- we have the density of air at STP,

The piston must be pushed more than the pressure inside the tyre:


∴The air cannot be made to flow in with the given pump at the given conditions.
