Fluid dynamics questions | form five Physics

A venture meter consists of two identical wide tubes A and B connected by a narrow tube C. The liquid enters through the wide tube A and after passing through the narrow tube C leaves through the other wide tube B. The entire arrangement is as shown in the following Figure.

Use the Bernoulli’s theorem at points 1 and 2, to show that an expression for the rate of flow of the liquid is given by , where all symbols carry their usual meaning.

A cylindrical tank 1 m in radius rests on a platform 5 m high. Initially, the tank was filled with water to a height of 5 m. If a plug of area 10​^-4​ m​² is removed by an orifice on the side of the tank at the bottom; calculate the initial speed with which the water:

1. flows from the orifice.
2. strikes the ground.
