A rectangular plate 1.25m * 2.4m is immersed in a liquid of relative density 0.85 with its 1.25m side horizontal and just at water surface . If the plane of the plate makes an angle of 60 degree with the horizontal , the pressure force on one side of the plate of
Answers
The pressure force on one side of the plate of 26.49 kN.
Explanation:
=> It is given that,
relative density of liquid = 0.85
Horizontal side of a rectangular plate = 1.25 m
Angle made by the plane of the plate = 60°
Pressure force = ?
=> For the given rectangular plate,
x bar = 2.4/2 sin60°
= 2.4/2 * √3/2
= 0.6√3
= 0.6 * 1.732
= 1.039 m
=> Pressure force on one side of the plate:
Force = ρ*g*A*x bar
= 850 * 10 * 1.25 * 2.4 * 1.039
= 26.49 kN.
Thus, the pressure force on one side of the plate is 26.49 kN.
