An incompressible liquid flows through a horizontal tube as shown in the following fig. Then, the velocity v of the fluid is

Horizontal tube of non-uniform cross-section has radii of 0.1 m and 0.05 m respectively at M and N for a streamline flow of liquid the rate of liquid flow is

A liquid is allowed to flow into a tube of truncated cone shape. Identify the correct statement from the following

The height of the dam, in an hydroelectric power station is 10 m. In order to generate 1 MW of electric power, the mass of water (in kg) that must fall per second on the blades of the turbine is

In the following fig. is shown the flow of liquid through a horizontal pipe. Three tubes A, B and C are connected to the pipe. The radii of the tubes A, B and C at the junction are respectively 2 cm, 1 cm and 2 cm. It can be said that the

A cylindrical tank has a hole of 1 cm² in its bottom. If the water is allowed to flow into the tank from a tube above it at the rate of 70 cm³/sec. Then, the maximum height up to which water can rise in the tank is

Two drops of the same radius are falling through air with a steady velocity of 5 cm per sec. If the two drops coalesce, the terminal velocity would be

A ball of radius r and density ρ falls freely under gravity through a distance h before entering water. Velocity of ball does not change even on entering water. If viscosity of water is η, the value of h is given by

The rate of steady volume flow of water through a capillary tube of length \'l\' and radius ‘r’ under a pressure difference of P is V. This tube is connected with another tube of the same length but half the radius in series. Then, the rate of steady volume flow through them is (The pressure difference across the combination is P)

A liquid is flowing in a horizontal uniform capillary tube under a constant pressure difference P. The value of pressure for which the rate of flow of the liquid is doubled when the radius and length both are doubled is
