Water Pressure on a Submersible's Porthole at a Depth of 1.5 km

At a depth of 1.5 km underwater, the pressure exerted by the water on the porthole of a submersible can be calculated using the formula for hydrostatic pressure, which is P = ρgh, where: - P is the pressure, - ρ is the density of the fluid (in this case, seawater), - g is the acceleration due to gravity, and - h is the depth of the fluid.

Given that the porthole has a diameter of 400 mm, we can calculate the pressure exerted by the water at a depth of 1.5 km.

Calculation

First, let's calculate the pressure exerted by the water at a depth of 1.5 km using the formula P = ρgh.

The density of seawater at the surface is approximately 1025 kg/m³, and the acceleration due to gravity is approximately 9.81 m/s².

Using these values, we can calculate the pressure:

P = (1025 kg/m³) * (9.81 m/s²) * (1500 m)

This calculation yields the pressure exerted by the water at a depth of 1.5 km.

Result

The pressure exerted by the water at a depth of 1.5 km can be calculated to be approximately 14.9 MPa (megapascals).

This means that at a depth of 1.5 km, the water exerts a pressure of about 14.9 million pascals on the porthole of the submersible.

I hope this helps! If you have further questions or need additional assistance, feel free to ask.
