Question

a circular plate of radius 5 meters is submerged in a 100 meter lake. calculate the hydrostatic pressure on the plate if the plate is lying horizontally and vertically.  

Answer 1

Pressure will not depend on the size of the plate

 

Pressure at a depth = Depth x density of liquid x g

 

= 100x 1000x9.8 N/m² = 9.8x 10⁵ Pa

 

Here density of water is taken as 1000kg/m³

 

(The force on the plate will depend upon its area and orientation)
