It water flows horizontally through a pipe of varying cross section and the pressure of water equals `10 cm` of g at a point where the velocity of flow is `40 cm//s`, what is the pressure at another point where the velocity of flow is `50 cm//s`?

Explanation

To solve the problem, we will use Bernoulli's equation, which relates the pressure, velocity, and height of fluid flow in a horizontal pipe. Since the flow is horizontal, we can ignore the height terms (H1 and H2) in Bernoulli's equation.

### Step-by-Step Solution:

1. **Write Bernoulli's Equation for Two Points:**
\[ P_1 + \frac{1}{2} \rho V_1^2 = P_2 + \frac{1}{2} \rho V_2^2 \]
