It never did that with the little vessels. At my direction, the GTE had used the same small diameter tubing we had been using on the smaller vessels to pump the new vessel to the old pressure source. To make matters worse, we needed more tubing length to connect this new larger vessel to the old pumping system. Talk about being in hot water. That was me! I had to fix this problem fast, as this temperature rise would destroy the product being processed, effectively rendering the technology, the company, and my job, useless.
The PhD biologists, biochemists, and chemists all came by the machine, felt the hot water in the large vessel, and shook their heads. They saw all their hard work to develop their molecules to do what they wanted them to do, being poached away by this big vessel. Their opinion was that I had somehow crossed the Rubicon, exceeded technological limits, or just plain screwed everything up completely. I could feel the heat and the pressure.
What could make water pumped through piping not get hot in a low-flow-rate situation and then get hot in a much higher flow rate situation? My conversation with Sherlock Ohms told me that head loss was the only physical mechanism that could explain conversion of the potential energy stored in the water as a result of being under sufficient pressure to move it down the pipe into heat during that journey down that pipe.
I can’t heat water without a source of energy, and there wasn’t any other source of energy I could find. I bounced the theory off of the PhD chemical engineer who had done his thesis on the high-pressure technology the company was based on. This engineer was intimately familiar with the laboratory scale hardware. He was skeptical of the head-loss theory.
He didn’t think that this water was being moved fast enough for measurable head loss. I accepted his input without comment. I thought about his perspective on using a hand-operated screw-plunger pump in order to pump liquid into a little vessel with his lab system. He is a very strong man who does rock climbing and kayaking.
Yet to fill the little lab vessels -- over about 25-30,000 psi -- his muscles would bulge out in the process of turning the wheel on the pressure generator. The automated system I developed had a multi-horsepower air-driven liquid pump that needed a 15HP air compressor to supply it with sufficient air to do its job.
