Question: The volume V of a liquid of viscosity coefficient $\eta$ delivered after time t when passed through a tube of length l and diameter d by a pressure p is given by

V = $\frac{p{{d}^{4}}t}{128\eta \,l}$

If the errors in V, p and l are 1%, 2% and 3% respectively, determine the error in $\eta$.
