Give the principle of working of venturimeter. Obtain an expression for volume of liquid flowing through the tube per second.

Obtain an expression for the rise of a liquid in a capillary tube.

Derive by the method of dimensions, an expression for the volume of a liquid flowing out per second through a narrow pipe. Asssume that the rate of flow of liwquid depends on (i) the coeffeicient of viscosity eta of the liquid (ii) the radius 'r' of the pipe and (iii) the pressure gradient (P)/(l) along the pipte. Take K=(pi)/(8) .

Derive an expression for pressure- volume work.

The diameter of a pipe at two points , where a venturimeter is connected is 8 cm and 5 cm and the difference of levels in it is 4 cm. Calculate the volume of water flowing through the pipe per second.

16cm^(3) of water flows per second through a capillary tube of radius a cm and of length l cm when connected to a pressure head of h cm of water if a tube of the same length and radius a/2 cm is connected to the same pressure head the quantity of water flowing through the tube per second will be-

The dimeter of a pipe at two point, where a venturimeter is connection is 9 cm 4 cm and the difference of level in it is 4 cm. Calculate the volumw of water flowing through the pipe per second.
