To study the laminar flow of a liquid through a narrow tube, the following formula is used `V=(pi P r^(4))/(8 eta l)`. Given P = 76 cm of Hg , r = 0.28 cm , V = 1.2 `cm^(2)s^(-1)` , l = 18.2 cm
If these quantities are measured to the accuracy of 0.5 cm of Hg, `0.01 cm, 0.1 cm^(3) s^(-1)` and 0.1 cm respectively, find maximum percentatge error in the value of `eta`.

A

B
