Answer:
The pressure that the water exerts on the bottom of the tank is 59.2 kPa
Explanation:
Given;
height of tank, h = 5m
height of water in the tank, = 4m
pressure at the top of the tank, = 20 kPa
The pressure exerted by water at the bottom of the tank is the sum of pressure on water surface and pressure due to water column.
Therefore, the pressure that the water exerts on the bottom of the tank is 59.2 kPa
