The following observations were made in an experiment noith Poiseuille's apparatus: Calculate the average velocity of water in a tube of radius 0.05 cm so that the flow is turbulent. Take, viscosity of water = 0.001 Pa s.

Explanation

To calculate the average velocity of water in a tube of radius 0.05 cm for turbulent flow using Poiseuille's law, we will follow these steps:

### Step-by-Step Solution:

1. **Identify Given Values:**
- Radius of the tube, \( r = 0.05 \, \text{cm} = 0.05 \times 10^{-2} \, \text{m} = 0.0005 \, \text{m} \)
- Viscosity of water, \( \eta = 0.001 \, \text{Pa s} \)
- Density of water, \( \rho = 1000 \, \text{kg/m}^3 \)
