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`0.1` m and `0.04` m and the pressure drop across its length is `10 Nm^(-2)`.

Explanation

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

### Step 1: Identify the Given Data
- Density of glycerine, \( \rho = 1.25 \times 10^3 \, \text{kg/m}^3 \)
- Radius at one end, \( r_1 = 0.1 \, \text{m} \)
- Radius at the other end, \( r_2 = 0.04 \, \text{m} \)
- Pressure drop, \( \Delta P = 10 \, \text{N/m}^2 \)
