A liquid flows through a horizontal pipe of varying cross section at a rate of 10 litres per minute. Find the velocity of liquid at a point where radius of pipe is 5 cm.

Explanation

To find the velocity of the liquid flowing through a horizontal pipe of varying cross-section, we can follow these steps:

### Step-by-Step Solution:

1. **Convert the flow rate from liters per minute to liters per second:**
\[ Q = 10 \, \text{liters/minute} = \frac{10}{60} \, \text{liters/second} = \frac{1}{6} \, \text{liters/second} \]
