Pressure at end of pipe with 14 gpm flow

In summary, the formula for calculating pressure at the end of a pipe is P = (Q * 60 * SG) / (A * v), where P is pressure, Q is flow rate in gallons per minute (gpm), SG is specific gravity, A is cross-sectional area of the pipe, and v is the velocity of the fluid. The flow rate of a pipe can be determined by measuring the amount of fluid (in gallons) that passes through the pipe in one minute. The pressure in a pipe is directly proportional to the flow rate, meaning that as the flow rate increases, the pressure also increases. The diameter of a pipe does not directly affect the pressure at the end, but a larger diameter pipe may result in a

I am trying to learn how to calculate pressure at the end of a pipe. The pipe is 2" PVc and has a flow rate of 14 gpm at teh end of a 35' run from the pump. How do I calculate pressure at this point?

What kind of pressure? Static pressure at the end of an open pipe is zero.
 

1. What is the formula for calculating pressure at the end of a pipe?

The formula for calculating pressure at the end of a pipe is P = (Q * 60 * SG) / (A * v), where P is pressure, Q is flow rate in gallons per minute (gpm), SG is specific gravity, A is cross-sectional area of the pipe, and v is the velocity of the fluid.

2. How do I determine the flow rate of a pipe?

The flow rate of a pipe can be determined by measuring the amount of fluid (in gallons) that passes through the pipe in one minute. This can be done using a flow meter or by timing how long it takes to fill a container of known volume.

3. What is the relationship between flow rate and pressure in a pipe?

The pressure in a pipe is directly proportional to the flow rate. This means that as the flow rate increases, the pressure also increases. Conversely, a decrease in flow rate will result in a decrease in pressure.

4. How does the diameter of a pipe affect pressure at the end?

The diameter of a pipe does not directly affect the pressure at the end of the pipe. However, a larger diameter pipe will have a lower fluid velocity, which can result in a lower pressure drop along the length of the pipe.

5. What is a typical pressure range at the end of a pipe with a flow rate of 14 gpm?

The pressure at the end of a pipe with a flow rate of 14 gpm can vary depending on factors such as pipe diameter, length, and fluid properties. However, a typical pressure range can be anywhere from 10 to 100 psi (pounds per square inch).
