A horizontal cylindrical vessel with a small orifice of area s is first filled with a liquid of density `rho` and then forced out through it by applying a constant force on the piston closing the cylinder. The time taken is t. The time taken is t. Calculate the work done.

A cylindrical vessel of area of cross section A is filled with a liquid up to a height H . A very small hole of area of cross section a is made at the bottom of the vellel. Find the time taken by the vessel to become empty.

A small ball of mass m and density rho is dropped in a viscous liquid of density sigma . Ather some time the ball falls with a constant velocity. Calculate the viscous force acting on the ball.

A large vessel of height H is filled with a liquid of density rho upto the brim. A small hole of radius r is made at the side vertical face, close to the base. The horizontal force is required to stop the gushing of liquid is

A horizontal cylinder of length l contains water. On the left a constant force F is applied on the piston and on the right there is a small hole of area a. What is the velocity of the piston? Hence, calculate the work done in emptying the vessel in time t . brgt given area of cylinder is A
