In a vessel as shown, the opening has a cross-sectional area ( mathrm{A} . F_{1} ) is the net force applied on the plate by liquid and air, which is kept to close the opening. The plate is now displaced a short distance away from the opening in which case liquid strikes the plate in elastically with a force ( F_{2} ). Find ( frac{F_{2}}{F_{1}} ) is

The liquid fills a space between two parallel plates, 1.4 cm apart.What force is required to move one plate past the other stationary plate with a velocity of 3.47 cm/s, if the moving plate has an area of 3.8 m2?Give your answer in Newtons unit.Viscosity is 5.13x 10-3 Pa.s

An x m high, 7 m wide rectangular plate fully emerges in the freshwater channel, as shown in the figure. The plate is hinged about a horizontal axis along its upper edge through point A and is restrained from opening by a fixed ridge at point B. Determine the force exerted on the plate by the ridge in kN.     P.S: The drawing is not drawn on an accurate scale.Here, x=9 m

A flat rectangular plate, dimension 1.5m length by 0:5m width is immersed in saline waterdensity 1025kg/m) such that their greatest and least depths are 1:80m and 0.80mrespectively. Determine the force exerted on one face by the water pressure.

Rat rectangular plate, dimension 1.5m length by 0.5m width is immersed inkaline water (density 1025kg / (m ^ 3) ) such that their greatest and least depths are 1.50m and 0.60m respectively. Determine the force exerted on one face by the water pressure.

A vertical plate is submerged in water and has the indicated shape.6 ft5 ft5 ft6 ftAn isosceles triangle is submerged in water pointed down. The base of 6 ft is horizontal and 6 ft below the surface of the water. The other two sides are each 5 ft.Express the hydrostatic force (in ft) against one side of the plate as an integral (let the positive direction be downwards) and evaluate it. (Assume that the weight density of this water is 62.5 lb/ft3.)
