    Pipe Water
In summary: The area of the pipe cross-section is 0.005square metres. So the length of pipe that holds one litre is 5000 metres.

Homework Statement



If water flows through a pipe at 0.8m/s , how many litres will flow through the pipe in 1 hour?

I think I may be greatly overthinking this question, I keep thinking I need to take into the account of the trench length which is 500m, and the pipe size which is 0.5m diameter.

Should I just m^2 * m/s = m*m*m / s = m³/s

Homework Equations



m^2 * m/s = m*m*m / s = m³/s
Pipe diameter: 0.5m
Trench length 500m (if relevent)

The Attempt at a Solution



I am just assuming the answer is:

0.8 x 60 = 48

48 x 60 = 2880

Therefore the answer is 2880m in an hour.
But I am not sure how to convert this to litres.


Should I use the velocity 0.8m/s and use dimensions?

Sorry, such an easy question that has confused me!

The length of the pipe has nothing to do with it. Given that the pipe is circular, wouldn't you expect ##\pi## to appear in the answer? Think of a circular slab of water that exits the pipe in 1 second. What would its volume be? That should get you started.

0.5pie x 0.8
=0.16 cubic metres/s
x 120
576l/hour

FYI, there are 1000 litres in a cubic metre.

What is the area of the pipe cross-section?
Using that, what length of pipe holds one litre?
 

1. How do I calculate the litres of water flowing through a pipe in 1 hour?

To calculate the litres of water flowing through a pipe in 1 hour, you need to know the diameter of the pipe, the velocity of the water, and the density of the water. The formula for this calculation is: Volume (litres) = π x (diameter (mm)/2)^2 x velocity (m/s) x 3,600 x density (kg/m^3). Make sure to use consistent units for accurate results.

2. Why is it important to calculate the litres of water through a pipe in 1 hour?

Calculating the litres of water through a pipe in 1 hour is important for determining the flow rate of the water. This information is crucial for designing and maintaining water systems, as well as for water conservation efforts. It can also help with troubleshooting any potential issues with the pipe or water supply.

3. What is the difference between flow rate and water volume?

Flow rate refers to the amount of water that passes through a pipe or system in a given amount of time, typically measured in litres per hour. Water volume, on the other hand, refers to the total amount of water in a system or container, typically measured in litres. Flow rate is a measure of how quickly water is moving, while water volume is a measure of the total amount of water present.

4. Can I calculate the litres of water through a pipe in 1 hour without knowing the velocity?

No, the velocity of the water is a crucial component in calculating the litres of water flowing through a pipe in 1 hour. Without this information, the calculation will not be accurate. The velocity can be measured using a flow meter or calculated based on the design of the pipe and the pressure of the water.

5. Are there any limitations to calculating the litres of water through a pipe in 1 hour?

Yes, there are some limitations to this calculation. It assumes a constant flow rate, so if the flow rate varies, the results may not be accurate. This calculation also does not take into account any potential blockages or restrictions in the pipe that could affect the flow of water. It is important to regularly monitor and maintain water systems to ensure accurate calculations.
