The kinematic viscosity of glycerin and kerosene are $1.2$ times and $0.95$ times of that of water, respectively. Glycerin and kerosene flow through two identical porous media having same hydraulic gradient. Assuming Darcy's law is valid for the porous media, the ratio of flow rate of kerosene to that of glycerin is
- $1.052$
- $1.140$
- $0.792$
- $1.263$
