Thank you for your help Travis! Greatly appreciated!

So how can I find the exact flow rate? The formula from engtoolbox.com is only for water with detailed properties. How did you arrive at the conclusion of being higher than 81 gpm?

Just to be sure, the tank will be filled from the top. Like filling a glass of water. So tank pressure, volume shouldn't matter?

The soda will discharge into a tank. The tank is covered, but with exhausts- basically atmospheric pressure, right? The tank is only used for storage.

Used the table on page 3-55 of a Cameron Hydralic Data book.

We got a recommended flow rate of 81.5gpm from a process engineer. Used kinematic viscosity of 50.97 centistokes to interpolate between 43.2 and 65.0 centistokes at 81.5gpm. Giving me ft loss/1000ft. Hope that answers your question..

I am a co-op. I have not taken fluid mechanics yet, sorry if I am having trouble understanding, and if I am stating the obvious. The railcar is closed. We'll force air into the vessel to push out the caustic. There are no measurement instruments. I have 283ft of straight pipe and a number of...

Would you like for me to email you the spreadsheet so you can see the formulas I used in the cells?

Thanks, Russ.

Sorry for misunderstanding guys. Check the attached snip shot. That's all the info I have. Length of pipe is 283ft from tank to furtherest unloading station. Tank is 30ft tall, top of railcar is 20ft.

Correction, total head loss is 25ft. Pressure is 17psi.

Travis, I've got all of the above. 17ft is my total head loss. Just need flow rate at 7psi through 3" pipe..

Essentially looking for flow rate from outlet pressure(7.81psi) in a 3" sch80 pipe.

I have head loss (25.95ft) and converted that to pressure (17.19psi). I am trying to find flow rate in 3" sch 80 pipe coming from railcar at 25psi. So outlet pressure is 7.813psi. The fluid is 50% Caustic soda.
