Question 1
A vertical triangular area with vertex downward and altitude 'h' has its base lying on the free surface of a liquid. The centre of pressure below the free surface is at a distance of
Question 2
As the depth of immersion of a vertical plane surface increases, the location of centre of pressure
Question 3
The cylinder and tube as shown in figure contains oil of specific gravity 0.85. For a gauge reading of 2.5 kg (f)/cm2, the total weight (in kN) of the piston and the slab placed on it is
Question 4
A triangular gate with a base width of 2 m and a height of 1.5 m lies in a vertical plane. The top vertex of the gate is 1.5 m below the surface of a tank which contains oil of specific gravity 0.8. Considering the density of water and acceleration due to gravity to be 1000 kg/m3 and 9.81 m/s2, respectively, the hydrostatic force (in kN) exerted by the oil on the gate is __________.
Question 5
A sector gate is provided on a spillway as shown in the figure. Assuming 
the resultant force per meter length (expressed in kN/m) on the gate will be _______ .
the resultant force per meter length (expressed in kN/m) on the gate will be _______ . Question 6
A three-dimensional gate having cross-section of a quarter cylinder is pivoted at the bottom O and is in static equilibrium when subjected to differential fluids of specific weight
