Section 4: Soil and Water Conservation Engineering

Fluid Mechanics

Subtopic: Ideal and real fluids, properties of fluids

Question Statement:

A fluid has dynamic viscosity $\mu = 0.002\text{ Pa}\cdot\text{s}$ and density $\rho = 800\text{ kg/m}^3$. Calculate its kinematic viscosity $\nu$ in $\text{m}^2/\text{s}$. (Enter value multiplied by $10^6$, i.e. $\nu \times 10^6$)

Answer Key:

2.5

Step-by-Step Solution & Explanation

$\nu = \frac{\mu}{\rho} = \frac{0.002}{800} = 2.5 \times 10^{-6}\text{ m}^2/\text{s}$ Value multiplied by $10^6$ is $2.5$.
