A loaded flatbottom barge floats in fresh water. The bottom of the barge is 4.46 m below the water line. When the barge is empty the barge's bottom is only 2.55 m below the water line. What is the difference between the pressure on the bottom of the loaded barge and the pressure at the water line?

The pressure difference between the pressure n the bottom of the loaded barge and the pressure at the water line is 18.73 KPa.

Explanation:

Bottom of the barge = 4.46 m

When barge is empty, bottom = 2.55 m

We know that

Pressure P = ρ g h

Pressure difference

ΔP = ρ g Δh

ΔP = 1000 x 9.81 x (4.46-2.55) Pa

ΔP=18.73 KPa

So the pressure difference between the pressure n the bottom of the loaded barge and the pressure at the water line is 18.73 KPa.
