Liquid Flow Calculation in 30ft System with Various Valve Sizes

AI Thread Summary
The discussion focuses on calculating liquid flow rates in a 30-foot system with various valve sizes and tubing diameters. The system consists of a 2-gallon container at the top, connected to a series of tubes leading to multiple valves. Key questions include determining the flow rate at one opening when all valves are opened versus when only one valve is opened. The complexity arises from the different diameters of the tubing and valves, which affect the overall flow dynamics. Accurate calculations are essential for understanding system performance and efficiency.

An entire system is filled with liquid.
At the top (30 feet) is a 2 gallon container,
connected to a tube (1.25" ID) for 14 feet,
connected to a tube (1.00" ID) for 10 feet,
then split with tees to 8 valves (.75" ID) and tubing (1.00" ID).

=O=O=O=O= valves

(sorry, the diagram on paper looks a lot better)

What is the flow rate at one opening if all valves are opened?
what is the flow rate at one opening is one valve is opened?

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...
