Velocity Formula for Fluid Flow

The velocity of fluid through a pipe can be calculated using the formula:

\( \text{Velocity} = \frac{\pi \times \left( \text{Pipe Diameter} \right)^2}{4 \times \text{Flow Rate}} \)

Velocity: This represents the speed at which the fluid flows through the pipe.
Pipe Diameter: The diameter of the pipe through which the fluid is flowing.
Flow Rate: The amount of fluid passing through the pipe per unit of time (e.g., liters per second or cubic meters per second).

The formula calculates the velocity of the fluid by considering the relationship between the cross-sectional area of the pipe (which depends on the square of the diameter) and the flow rate (the volume of fluid per unit of time). By dividing the area of the pipe by the flow rate, we can determine the velocity.

Water Velocity Calculation

Water is flowing through a 10-centimeter diameter pipe at a rate of 9 liters per second. What is the water velocity?

Steps:

Enter 10 in the pipe diameter box and choose centimeters from its menu.

Enter 9 in the flow rate box and choose liters per second from its menu.

Click the CALCULATE button and the answer is 114.59 centimeters per second.
