Test: Hydrostatic Force on Surface - Civil Engineering (CE) MCQ

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)

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

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
