    Calculating the PSI needed to generate a certain fluid speed

    Nothing new about this picture that you don't already know, just a glimpse of what we are dealing with. This is only at 50cm boom height. We are generally closer to 8-10feet above the crop canopy. Moving on average of 150MPH ground speed. For herbicide applications I want to be able to 'draw a...

    Calculating the PSI needed to generate a certain fluid speed

    Yes, we are working on a few prototypes. running my nozzle next to what I currently have installed on my plane right now, there is a great deal of difference. Its a tip that I believe will reduce physical drift from spray planes. running some ground tests, nothing super scientific about it...

    Calculating the PSI needed to generate a certain fluid speed

    I guess I am having a hard time relaying what I want to find out. I have since found this much out, It will take 3.33 GPM moving through a 2mm diameter orifice to reach a velocity of 150mph. What PSI would achieve this?

    Calculating the PSI needed to generate a certain fluid speed

    If you can come up with some numbers i would love to see them, i came up with 79.1295 MPH at 50PSI with a flow rate of 2.24GPM. This is a little bit advanced for me, and really don’t know if i am even in the ballpark. Was hoping to get some answers from the science community on here. This is...

    Calculating the PSI needed to generate a certain fluid speed

    this is on a constant pressure spray boom. Were my nozzles mount to the boom. in place of one of the nozzles i have a pressure gauge, so i know at that point in the system i am getting 50 psi. It does go through a nozzle body with a diaphragm and would be nearly impossible for me to explain the...

    Calculating the PSI needed to generate a certain fluid speed

    Or let’s just say, the pipe is 1/4” under 50 psi. reduces to the 2mm orifice that is spraying a straight stream, how fast is that stream of water moving?

    Calculating the PSI needed to generate a certain fluid speed

    Give me all the parameters you need to solve the problem.

    Calculating the PSI needed to generate a certain fluid speed

    Well let’s not make this any more complicated than we need to... let’s just use water, and the pressure needed at the point it exits the orifice.

    Calculating the PSI needed to generate a certain fluid speed

    How much pressure in PSI would it take to generate 150mph stream out of a 2 mm perfectly round orifice? And how many GPM would that equate to? Thanks for any help

    And I don't totally disagree with you about us wasting our time. . A heck of a lot of people with a lot more education have spent fortunes to develop spray equipment.. I just wanted to see what the numbers were and see what happens

    Yes sir, speed is in MPH. Orifice is .12 inch flat fan. Also if the flat fan doesn't work with the math I have a .12 inch straight stream to work with. Gallons are 3.785 Thanks for the help

    Ha, I am a pilot. And the discussion came up the other day amongst myself and a few colleagues, also pilots, about this discussion. The theory that the PSI on the fluid moving straight back, that if you could essentially push it out at 145 MPH and you were flying 145 MPH the opposite direction...

    I already know about the rotary atomiser systems. I really just want to figure out what PSI I would need with the parameters stated. Planning to do some real world tests and would like to have a concrete number to start with

    So... do you know what the math would be? To find that PSI?
