If you don't know how long it took to move 100 gallons, you don't have a flow rate. Flow rate is volume per time unit.

The internet knows where all the good music is. 🎼🎵🎶

I don't know how I would replace those valves on a tech school budget. The workstations are over 35 years old (and look it). If I had to, I could get three two way valves all actuated at the same time to replace one Valco.

perfect.

agreed

Yes

Faaaaaax

Can’t argue

I know now. We just couldn't see the forest for the trees.

Never had the pleasure of seeing them. So jealous.

I'll see what I can do here, but THE MUSIC STAYS ON! Besides, you'll just make fun of my Texas drawl. This is for a class simply called Analyzers. A lot of our graduates get hired at refineries, chemical plants, and midstream pipeline companies. All of those industries and many more have some type of chromatograph. In the energy business, the gas to be analyzed is some form of hydrocarbon mix like natural gas. The students learn about each component. They must map the port connections on the sample valve in its energized and de-energized state. We test the valve, take it apart, clean it, re-assemble it and test it again by tubing each port to a beaker of water to look for bubbles. Once assembled, we'll use soapy water to test for leaks. We used to pack our own columns, but the success rate was low and the mess was just too much, so we use columns that are pre-tested. We use thermal conductivity detectors as part of a Wheatstone Bridge with a potentiometer for balancing. The hardest part for my students is getting the flows right, especially when they decide to turn on the power supply. We've lost som TC detectors because some sleepy student forgot to set the flows when he/she turned on the power. We get the best results with very low flows and the PLC analog input set for a range of 3V - 6V. We have recently switched to a test gas of nitrogen, CO2, and helium. We get two good peaks on the PLC's chart recorder (ControlLogix PLC). The old test gas was a hydrocarbon mix with a particularly offensive odorant, so it had to be vented outside. Our new gas is harmless in small amounts and odorless so small sample gas leaks aren't an issue. In the future, I'd like to expand our workstation collection to include Flame Ionization Detectors. Hope this helps.

Scottie Young. Here's a newer one with Scottie, different song. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OJNEv2jVhoE.html

Thank you, sir.

I think they're trying to say "chinga guey." Slang Spanish for "untrustworthy person" or "thug." I believe Juanitos is actually a French group and sometimes they struggle with English or Spanish. Still wonderful music.

@@farfrohmpupen i saw u r reply now. thx :)

A strange lost technology from long ago...

Juanitos cooks!

he/she does? wow!

Same

Me

Yes ik

Here, here.

Shouldn't the word "Chungaye" be translated "Chunt guey?" It's Spanish slang for "chuntaro" meaning "ghetto-class," and "guey" meaning "dude." In other words, the shady guy dealing at a party. I also heard "casa nova" in there, too: "new house." The song seems to be about a kid from divorced parents who have suspicious affluence thanks to gangster side-gigs and he doesn't know who his real dad is.

great now I can sing along to this ear worm.
