Shown in the figure is a container whose top and bottom diameters are D and d respectively At the bottom of the container these is a cappillary tube of outer radius b and inner radius a. the volume flow rate in the capillary is Q. if the capillary is removed the liquid comes out with a velocity of `v_(0)`. The density of the liquid is given as calculate the coefficient of viscosity `eta` (given `pia^(2)=10^(-6)m^(2)` and `(a^(2))/(l)=2xx10^(-6)m`]

A liquid of density 900(kg)/(m^(3)) is filled in a cylindrical tank of upper radius 0.9 m and lower radius 0.3 m A capillary tube of length 1 is attached at the bottom of the tank as shown in fig. The capillary has outer radius 0.002 m and inner radius a. When pressure P is applied at the top of the tank volume flow rate of liquid is 8xx10^(-6)(m^(3))/(s) and if capillary tube is detached, the liquid comes out from the tank with a velocity 10(m)/(s) . then the coefficient viscosity of liquid is (pia^(2)=10^(-6)m^(2)a^(2))/(l=2xx10^(-6)m) .
