In Poiseuilli's method of determination of coefficient of viscosity, the physical quantity that requires greater accuracy in measurement is

Text Solution

Verified by Experts

Formula `Eta=(piPr^(4))/(8VI)` the inner radius of the capillary tube appears with a 4th power in the equation. So if there is an error it becomes 4 times. Hence inner radius must be measured with high accuracy
