A sealed air spring in a suspension test rig contains a fixed mass of air. An additional load compresses the air spring.
The temperature of the air remains constant.
| condition | pressure in kPa | volume in litres |
|---|---|---|
| before the additional load is applied | 250 | 18 |
| after the additional load is applied | 450 | to be calculated |
Calculate the volume of the air spring after the additional load is applied.
Use the equation
p1×V1=p2×V2p_1 \times V_1 = p_2 \times V_2p1×V1=p2×V2
