Consider the Venturi meter of Fig. 16-8, containing water, without the manometer. Let A₁ =4.75A₂. Suppose that the pressure at point 1 is 2.12 atm. (a) Compute the values of v₁ at point 2 equal to zero. (b) Compute the corresponding volume flow rate if the diameter at point 1 is 5.20 cm. The phenomenon at point 2 when p₂ falls to nearly is zero is known as cavitation. The water vaporizes into small bubbles.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
