How to Calculate Volume Flow of Water in a Pipe

What is the formula to calculate the volume flow of water in a pipe?

How many litres of water flows out of a pipe having an area of cross section 5 cm square in 1 minutes if the speed of water in the pipe is 30 cm per second ?

Answer:

The volume of water flowing out of the pipe per minute is 9 litres.

To calculate the volume flow of water in a pipe, you can use the formula:

Volume Flow (Q) = Cross-sectional Area (A) * Speed (v)

Given that the area of cross section of the pipe is 5 cm square and the speed of the water is 30 cm per second, you can plug in these values into the formula to find the volume of water flowing out of the pipe per minute.

This is calculated using the formula for the volume flow and converting the result from cubic centimetres per second to litres per minute.

For a more detailed explanation, let's break it down into steps:

1. Calculate the volume flow per second: 5 cm^2 * 30 cm/s = 150 cm^3/s
2. Convert cubic centimeters to litres: 1 cm^3 = 0.001 L
3. Calculate the litres of water flows out of the pipe in 1 minute: 150 cm^3/s * 0.001 L/cm^3 * 60 s/min = 9 L/min

By following these steps and using the formula for volume flow, you can determine the amount of water flowing through a pipe per minute.
