A maintenance robot moves vertically through a tank containing one liquid.
The table shows the result of the first test.
| Starting depth | Finishing depth | Increase in pressure due to the liquid |
|---|---|---|
| 0.50 m | 1.30 m | 6800 Pa |
Gravitational field strength, g=10 N/kgg = 10\ \text{N/kg}g=10 N/kg.
The second test covers the section of the tank from 1.30 m to 2.00 m below the surface.
Calculate the increase in pressure during the second test.
