Question

A submarine descends to a depth of 200m in the ocean. If the pressure at the surface is 101000Pa, what is the pressure at this depth? (Density of seawater = 1030kg/m³).

Answer 1

To calculate the pressure at a depth of 200m in the ocean, we can use the formula for pressure in a fluid:

Pressure = Pressure at the surface + Density of fluid * g * Depth

Where:
Pressure at the surface = 101000 Pa
Density of seawater = 1030 kg/m³
g = acceleration due to gravity = 9.81 m/s²
Depth = 200 m

Plugging the values into the formula:

Pressure = 101000 + 1030 * 9.81 * 200
Pressure = 101000 + 2026860
Pressure = 2127860 Pa

Therefore, the pressure at a depth of 200m in the ocean is 2127860 Pa.
