Developing Pump Performance Curves

AI Thread Summary
Developing pump performance curves for pulp slurries in a closed-loop lab-scale pipeline requires measuring head versus flow rate at constant RPMs. The challenge arises from the inability to discharge slurry, unlike pure water experiments. Participants suggest using a larger pump to facilitate flow adjustments while maintaining constant RPMs. Additionally, applying pump scaling laws can help translate results from the larger pump back to the original system. Effective methods for achieving this in slurry systems remain a key focus of the discussion.

Hi Folks;

I am developing a series of pump performance curves for pulp slurries. I am running a closed-loop Lab-Scale pipeline facility. My question is about measuring head vs. flow rate at constant RPMs. I did it for pure water by continuously feeding the system with water, and gradually opening the discharge valve of the loop, while the RPM was kept constant, to record data for various flow rates. However, I can not do it for slurry, as I can't discharge it.

I see people have done it in papers, but I do not know how. I would really appreciate if you could help me. So here I rewrite the question:

On a closed-loop pipeline, how can I gradually increase/decrease the flow rate, while keeping the pump RPM constant ?

Thanks;

Use a bigger pump and translate your results with the pump scaling laws?
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
