Post Utme Caleb University 2020 Physics Question 34 diagram

A fluid of density $\rho$ is flowing through a horizontal pipe of radius $R$. The fluid's velocity is given by $v = \frac{1}{4} \frac{\Delta P}{\eta} \frac{R^2}{h}$, where $\Delta P$ is the pressure difference across the pipe, $\eta$ is the fluid's vis\cosity, and $h$ is the height of the pipe. What is the fluid's volume flow rate?

Answer Options

Correct Answer A. \frac{\pi R^4 \Delta P}{8 \eta h}
B. \frac{\pi R^3 \Delta P}{4 \eta h}
C. \frac{\pi R^2 \Delta P}{2 \eta h}
D. \frac{\pi R \Delta P}{\eta h}
Correct Answer
A
Correct Option:
\frac{\pi R^4 \Delta P}{8 \eta h}
