Question

Reynold's number R which determines the condition for streamline flow of a liquid through a tube depends upon.

Answer 1

Reynold's number$\left(Re\right)=\frac{InertiaForce}{viscousforce}=\frac{\rho vd}{\mu }$.

Here $\rho$=Density and $v$=average velocity and $d$=characteristic length

Hence from the above equation we can say that reynold's number depends upon the inertia force

as well as viscous force of the fluid.
