Calculate the rate of flow of glycerine of density. `1.25xx10^(3) kg//m^(3)` through the conical section of a pipe. If the radii of its ends are `1.0m` and `0.04m` and the pressure drop across its length is `10N//m^(2)`.

Explanation

To solve the problem of calculating the rate of flow of glycerine through a conical section of a pipe, we will follow these steps:

### Step 1: Identify Given Values
- Density of glycerine, \( \rho = 1.25 \times 10^3 \, \text{kg/m}^3 \)
- Radius at the larger end, \( r_1 = 1.0 \, \text{m} \)
- Radius at the smaller end, \( r_2 = 0.04 \, \text{m} \)
- Pressure drop across the length, \( \Delta P = P_1 - P_2 = 10 \, \text{N/m}^2 \)
