Matt, There videos are great! thank you for taking the time to put these together I feel really confident going into a Driver/Engineer test! Thank you, Anthony Brown

@Boxalarmtraining 2 года назад

Thanks!

@joelbeard9480 Год назад

Thank you! This simplifies this so so much.

Thank you for saving me on my DE test!

Great explanation thank you!

This cleared up SO MUCH for me in my hydraulics class. Thanks a ton! Must have missed something that my instructor said while taking notes.

Thanks

Why do we need to close the(discharge) isolation valve of a centrifugal pump during startup⁉️ #pumpsolutions #pump #discharge #startup #energy #oilandgas #hazard #saftey #gas #renewableenergy techproces.com/centrifugal-pump/

Kinda funny but straight up... Going though chauffer school, my dad's friend said 150 psi at the pump... when you do the math on a 2 1/5 or 1 ³/4 its actually a great starting point and after that adjust you valves or governer and your good to go

@Boxalarmtraining 5 лет назад

150 is a very good starting point for the vast majority of operations.

What about residual pressure for the last problem

@whoopwhoop3777 5 лет назад

I watched this video in training today and halfway through the only thing I could think of is punching you in your face. 😂

@Boxalarmtraining 5 лет назад

I never thought shooting this video could cause me pain and suffering in that way.

How did you get the 500 gpm for the last practice problem?

@davidw555 3 года назад

it was given as part of the problem.

@jonathanbosco8458 9 лет назад

Thanks Sir

@mitchellbaxter5189 6 лет назад

For the LDH equation. Where did you get the 500gpm from? I guess I'm just not understanding how you got the flow without a nozzle pressure.

@bryandavies5084 5 лет назад

He is only figuring out the Friction Loss. Like he says it could be going to a nozzle, another fire engine, ladder truck, etc. "Pressure" is added when you figure out your total Pump Discharge Pressure, that's when you need to know what pressure you want at the end of your hose. My Pump Discharge Pressure (PDP) formula is PDP = Nozzle Pressure (NP) + Friction Loss (FL) = Appliance Loss (AL) + or - Elevation (EL). He is only helping you get one piece of information (Friction Loss) to ultimately determine what to set your Pump Discharge Pressure at. Here's an example. 200' 1.75" hose with a fog nozzle, operates at 100 PSI, and I want it to flow 125 GPM. Nozzle Pressure is 100 Friction Loss is 48 Appliance loss is 0 Elevation loss/gain is 0 PDP = 100 + 48 + 0 + 0 Set your pressure gauge on your engine/truck at 148

I believe he is looking at the 500 gpm as his target flow much like how we commonly use 150 gpm when talking about 1 3/4 lines (even thought we know that without flow testing our hose and nozzle packages, we do not actually know how much water we are flowing).
