An inspection camera is lowered into a tank containing hydraulic oil.
The camera is positioned below the surface of the oil.
| quantity | value |
|---|---|
| vertical depth of the camera | 2.0 m |
| density of the hydraulic oil | 850 kg/m3 |
| gravitational field strength | 10 N/kg |
Calculate the rise in pressure between the oil surface and the camera.
Use the equation
P=h×ρ×gP = h \times \rho \times gP=h×ρ×g
