Question 44
Easy

A pressure sensor is positioned at a depth, hhh, below the surface of the water in a large reservoir.

A diagram showing a cylindrical reservoir filled with water. A pressure sensor is mounted on the wall at a depth, h, below the surface of the water. A vertical double-headed arrow indicates the distance h from the water level down to the level of the sensor.

The density of the water is 1000 kg/m3 and the gravitational field strength, ggg, is 10 N/kg.

The pressure due to the water column at the sensor is 36 kPa (36,000 Pa36,000\text{ Pa}36,000 Pa).

Calculate the depth, hhh, of the pressure sensor.

Use the equation:

pressure=depth×density×gravitational field strength \text{pressure} = \text{depth} \times \text{density} \times \text{gravitational field strength} pressure=depth×density×gravitational field strength
