Question

A A Square Plate af side som is placed horizontally am below the surface of water Atmospheric pressure is to Nm ? calculate the total thrust on the plate Griven density Given density of Waterloooleg m2 and flom 2​

Answer 1

Answer:

explanation

Given, h=1m,ρ=103kgm-3, g=9.8ms-2

Atmospheric pressure P0=1.013×105Nm-2

area of plate =10m×10m=102m2.

Total pressure at a point below the surface of water = atmospheric pressure + pressure due to the column of water

P0+hρg

=(1.013×105)+(1×103×9.8)

=1.111×105Nm-2

∴ Total thrust on the plate = Pressure × Area of plate

=(1.111×105)×102

=1.111×107N.
