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

or a sliding plate viscometer of the type we have discussed in class, it is found that when the distance between the plates is 2 mm, a shearing stress of 150 Pa develops at the upper plate when it is pulled at a velocity of 0.5 m/s. The viscosity of the Newtonian fluid between the plates is:

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

A 5.00 kg object is released from rest while fully submerged in a liquid. The liquiddisplaced by the submerged object has a mass of 3.00 kg. How far and in what directiondoes the object move in 0.200 s, assuming that it moves freely and that the drag force onit from the liquid is negligible?

A water jet strikes a stationary vertical plate horizontally at a rate of 5 kg/s with a velocity of 35 km/h. Assume the water stream moves in the vertical direction after the strike. What is the magnitude (absolute value) of the force needed to prevent the plate from moving horizontally? Express your answer in N.

A container has a large cylindrical lower part with a long thin cylindrical neck. The lower part of the container holds 12.5 m3 of water and the surface area of the bottom of the container is 5.00 m2. The height of the lower part of the container is 2.50 m and the neck contains a column of water 8.50 m high. The total volume of the column of water in the neck is 0.200 m3. What is the magnitude of the force exerted by the water on the bottom of the container?
