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?

Respuesta :

Answer:

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.
