Question

The total pressure (hydrostatic force) on a circular plate of 2m dia immersed horizontally in water at a depth of 1 m is a. 39.24kN, b.19.62kN,c.30.76kN, d.9.81kN​

Answer 1

Answer30.76

Explanation:

Answer 2

Explanation:

• So the total pressure on a circular plate will bee P = ꝭ g x bar
• Also the total horizontal force Fh = ꝭ g A x bar
• Now ꝭ is density of liquid = 1000 kg/m^3
• So g is the acceleration due to gravity = 9.81
• So x bar is depth of centre of gravity = 1m
• Diameter of the circular plate d = 2m
• So the total area of surface = A
• Now area A = Π/4 x d^2
•                     = Π/4 x 2^2
•                  A = Π
• So the centre of pressure is acted upon by the horizontal force and hence centre of gravity is taken.
• So Fh = ꝭ g A x bar
•            = 1000 x 9.81 x Π x 1
•           = 30831.4 N
•            = 30.83 KN
