The rate of flow of a liquid through a capillary tube of radius r is under a pressure difference of P. Calculate the rate of flow when the diameter is reduced to half and the pressure difference is made 4 P?

The rate of flow of a liquid through a capillary tube of radius r is u

1.	The rate of flow of a liquid through a capillary tube of radius r is under a pressure difference of P. Calculate the rate of flow when the diameter is reduced to half and the pressure difference is made 4 P?
Answer» SOLUTION :` Q_2 = pi xx 4 P xx (D//2) ^(4)//8 xx 2^(4)xx ETA l = 1//4`
