Flow rate of water out of a pipe

In summary, the conversation discusses the calculation of flow out of a 12 inch pipe in a 90 acre man made lake that is approximately 10 feet deep. The theoretical speed is determined by the formula √(2gh/ρ), where g is 9.81 cm/sec2, h is the difference in height between the surface of the lake and the far end of the pipe, and ρ is the density of water.

Hello,
Am the owner of a 90 acre man made lake and am trying to calculate the flow out of 12 inch pipe at the bottom of the lake. The lake is approximately 10 feet deep. Can someone point me in the right direction on how to solve this question?

Hello Caerus1! Welcome to PF! :smile:

If it's a real pipe, it's probably blocked, but the theoretical speed is √(2gh/ρ), where g is 9.81 cm/sec2, h is the difference in height between the surface of the lake and the far end of the pipe, and ρ is the density of water. :wink:
 

1. What factors affect the flow rate of water out of a pipe?

The flow rate of water out of a pipe is affected by several factors, including the diameter and length of the pipe, the pressure and volume of the water, and any obstructions or restrictions in the pipe.

2. How is the flow rate of water out of a pipe measured?

The flow rate of water out of a pipe is typically measured in gallons per minute (GPM) or cubic feet per second (CFS). This can be measured using a flow meter, which calculates the rate of flow based on the velocity of the water through the pipe.

3. What is the relationship between pressure and flow rate of water out of a pipe?

The pressure of the water in a pipe directly affects the flow rate. Higher pressure will result in a faster flow rate, while lower pressure will result in a slower flow rate. This is due to the fact that pressure is what pushes the water through the pipe, so a higher pressure means more force and therefore a faster flow rate.

4. How can the flow rate of water out of a pipe be increased?

The flow rate of water out of a pipe can be increased by increasing the pressure of the water, increasing the diameter of the pipe, or reducing any obstructions or restrictions in the pipe. Another method is to add a pump to increase the pressure and force of the water through the pipe.

5. What is the importance of understanding the flow rate of water out of a pipe?

Understanding the flow rate of water out of a pipe is important in many industries, including plumbing, irrigation, and manufacturing. It allows for efficient and effective use of water, and can also help troubleshoot any issues with the water supply system. In addition, knowledge of the flow rate can help ensure proper maintenance and prevent damage to the pipes.
