Question 43
Easy

The diagram shows an autonomous underwater vehicle (AUV) submerged in seawater.

An autonomous underwater vehicle with a highlighted circular viewport window

Calculate the magnitude of the force that the seawater exerts on the flat circular window of the optical camera viewport.

fluid pressure of seawater on the window=5.7×106 Pa \text{fluid pressure of seawater on the window} = 5.7 \times 10^6 \text{ Pa} fluid pressure of seawater on the window=5.7×106 Pa area of the flat circular viewport window=4.2×10−5 m2 \text{area of the flat circular viewport window} = 4.2 \times 10^{-5} \text{ m}^2 area of the flat circular viewport window=4.2×10−5 m2

Use the equation:

force=pressure×area \text{force} = \text{pressure} \times \text{area} force=pressure×area

Give your answer to 2 significant figures.
