One end of a twodimensional water tank has the shape of a quadrant of a circle of radius 2 m. When the tank is full, the vertical component of the force per unit length on the curved surface will be
When the water surface coincides with the top edge of a rectangular vertical gate 40 m (wide) x 3 m (deep), then the depth of centre of pressure is
Depth of centre of pressure,
h_{p} = 2d/3 = (2 x 3)/3 = 2 m
In which of the following arrangements would the vertical force in the cylinder due to water be maximum
Vertical force will be maximum when the cylinder is completely submerged in water.
An isosceles triangular plate of base 3 m and altitude 3 m is immersed vertically in an oil of specific gravity 0.8. The base of the plate coincides with the free surface of oil. The centre of pressure will lie at a distance of (from free surface)
Depth of pressure (h*) from free oil surface is given by,
A vertically immersed surface of size b x d has its width b parallel to the water surface and depth of its centroid from the water surface is The distance of its centre of water pressure from the water surface is
Centre of water pressure,
For a vertical semicircular plate submerged in a homogeneous liquid with its diameter ‘d' at the free surface, the depth of centre of pressure from the free surface is
The position of centre of pressure on a plane surface immersed vertically in a static mass of fluid is
A vertical rectangular plane surface is submerged in water such that its top and bottom surfaces are 1.5 m and 6.0 m respectively below the free surface. The position of centre of pressure below the free surface will be at a distance of
The horizontal component of force on a curved surface is equal to the
A circular plate of diameter d is submerged in water vertically, so that the topmost point is just at the water surface. The centre of pressure on the plate will be below the water surface at a depth of
