Question

.A large fish tank is filled with water. The pressure on the base of the fish tank is 4000N/m^2. The base of the tank is a rectangle measuring 2m x 4.5m (a) Calculate the area of base.

Answer 1

F = 36 kN

Explanation:

It is given that,

The pressure on the base of the fish tank is 4000N/m².

The base of the tank is a rectangle measuring 2.0m by 4.5m.

Area of the base of the tank is 9 m²

We need to find the force on the base caused by the base of the water. Pressure on the base of the tank is given by the force acting per unit area such that,

\begin{gathered}P=\dfrac{F}{A}\\\\F=P\times A\\\\F=4000\times 9\\\\F=36000\ N\\\\F=36\ kN\end{gathered}

P=

A

F

F=P×A

F=4000×9

F=36000 N

F=36 kN

So, the force of 36 kN is acting on the base by the base of water
