What is the pressure change in this wash nozzle?

In summary, the conversation discusses the selection of nozzles for a wash system, with the pump having a flow rate of 20 GPM at 1000 PSI and 20 nozzles connected to a 1" pipe. It is suggested that the 1/4" nozzle selected may be too large for the desired 1 GPM at 1000 PSI, and the correct pressure can be achieved by selecting a different nozzle or adjusting the pump characteristics.

I have one question about the many wash nozzles.
The pump has 20 GPM @ 1000 PSI , the pipe size is 1" and connect 20 nozzles.
So the 1/4" nozzle may be 1GPM @ 1000 PSI. But the nozzle standard show the 1GPM is about 10 PSI.
and 1000psi need 10 GPM.
Can anyone know how to calculate the nozzle right pressure ?

You have selected a nozzle that is way too large for your application. If 1gpm at 1000 psi is what you want, there is nothing to calculate; you just select a nozzle that has that performance.

If 1000psi isn't what you want, decide what you want and select system components that will provide it (you may need a different pump too).

That depends on your pump characteristics. If your pump flows 20GPM regardless of pressure, you'll end up with only 10psi in your system, with each nozzle flowing 1GPM. If your pump flows more at lower pressure, you'll end up somewhere above 20GPM and somewhere between 10 and 1000psi. If you want 1000psi in your system, you'll either need a pump that flows 200GPM or nozzles that are much smaller. Alternatively, you could use a pair of your current nozzles and your current pump.
 

1. What is pressure change?

Pressure change refers to the difference in pressure between two points in a system. In the context of a wash nozzle, it is the change in pressure between the inlet and outlet of the nozzle.

2. Why is pressure change important in a wash nozzle?

Pressure change is important in a wash nozzle because it determines the force and velocity of the water spray. A higher pressure change will result in a stronger and faster spray, while a lower pressure change will result in a weaker and slower spray.

3. How is pressure change measured in a wash nozzle?

Pressure change in a wash nozzle is typically measured using a pressure gauge. This device measures the difference in pressure between the inlet and outlet of the nozzle and displays it in units of pressure, such as pounds per square inch (psi).

4. What factors can affect pressure change in a wash nozzle?

Several factors can affect pressure change in a wash nozzle, including the size and shape of the nozzle, the flow rate of the water, and the pressure of the water source. Other external factors, such as clogs or obstructions in the nozzle, can also impact pressure change.

5. How can pressure change be adjusted in a wash nozzle?

Pressure change can be adjusted in a wash nozzle by changing the flow rate of the water or by adjusting the pressure of the water source. Additionally, using different nozzle sizes or shapes can also affect pressure change. It is important to carefully adjust pressure change to achieve the desired spray force and velocity without damaging the nozzle or the surface being washed.
