A volume V of a viscous liquid flows per unit time due to a pressure head `DeltaP` along a pipe of diameter d and length l. instead of this pipe a set of four pipes each of diameter `(d)/(2)` and length 2l is connected to the same pressure head `DeltaP`. Now the volume of liquid flowing per unit time is:

A pipe of diameter d can drain a certain water tank in 40 minutes. The time taken by a pipe of diameter 2d for doing the same job in :

A 16cm^(3) volume of water flows per second through a capillary tube of radius r cm and length l cm , when connected to a pressure head of h cm of water. If a tube of same length and radius r//2 is connected to the same pressure head, find the mass of water flowing per minutes through the tube.

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-

A 16cm^(3) of water flows per second through a capillary tube of radius r cm and of length 1 cm, when connected to a pressure head of h cm of water. If a tube of the same length and radius r//2 is connected to the same pressure head, find the mass of watear flowing per minute through the tube.

When a capillary tube is connected to a pressure head quantity of water flows per secind is V (in c.c.) if another tube of same length but half the radius is connected to the first in series to the same pressure head, the quantity of water flowing through them per sencond will be (in c.c)

A pipe having an internal diameter D is connected to another pipe of same size. Water flows into the second pipe through n holes, each of diameter d. if the water in the first pipe has speed v, the speed of water leaving the second pipe is

Water flows through a capillary tube of radius r and length l at a rate of 40 mL per second, when connected to a pressure difference of h cm of water. Another tube of the same length but radius r//2 is conncected in series with this tube and the combination is connected to the same pressure head. Calculate the pressure difference across each tube and the rate of flow of water through the combination.

A large container is continually filled with a viscous liquid that flows from two equally long , cylindrical pipes , labeled A and B , onto a conveyer belt as shown in the figure . The diameter of pipe B is 1.75 times larger than that of pipe A . What is the ratio of the average volume flow rate of the liquid exiting pipe B to that of the liquid exiting pipe A ?

The rate of flow of the liquid through the tube of length l and radius r, connected across a perssure haed h be V. If two tubes of the same length but of radius r and r//2 are connected in series, across the same pressure head h, find the rate of flow of liquid through the combination. If both the tubes are connected inparallel to the same pressure head, then find the rate of flow of liquid through the combination.
