@ProEpro "Like has already been said you are completely ignorant about what you are trying to do." Well I don't think it had been put quite like that already. If I already knew how to do the calculations or knew about vacuum that much, I wouldn't be here on a forum asking questions. Thanks...

All of these answers make sense. Thanks! Lets say I have this pump listed above. Then the 5" pipe running out to a 6.68 cubic feet tank at each machine. On both sides of the tank is a valve to close it off. The tank is vacuumed down to -29 inHg while the valve between the tank and the chamber...

The vacuum pump is this: Quincy Compressor Model QSVI-75 - HP Rotary Screw Vacuum Unit rated for 980.0 ACFM and 29.9" HgV ultimate vacuum. Product Features • Voltage: 460/3/60 • Control Type: Auto Dual • Full Voltage Motor Starter - Mounted & Wired • EPACT High Efficiency Drive Motor • Full...

I have a question on vacuum. I have searched every reference I can find on it and can't seem to get what I am looking for. I have a chamber of sorts that is .25 CF. I need to draw it down to as near perfect vacuum as possible. My Vacuum Pump specs are 98.0ACFM and 29.9"HgV. There is a 5"...

The light and buzzer are a good idea. I hadn't even noticed the gauge quit working before the oil caught fire. Thanks for the idea and thanks for the info on the ground bus. I was trying to clean it up with the ground bus. @bradrs This is exactly what I am looking for. Do you happen to know a...

I haven't had the chance to rewire the ground to the engine yet. No thread tape to interfere with the connection. It does have a brass reducer that takes it from 1/4 NPT to 1/8 NPT. I dont think the brass is the issue though. It reads the correct resistance with the key off and probing the...

Thanks! I was measuring with a DMM from a terminal on the sender to a ground under the dash. That is the same place the gauge is / was grounded. I messed with it today. The sender used the threads and engine block as a ground. I connected a hose clamp around the sender with a wire under it...

I have an old dump truck. It had a mechanical oil pressure gauge. The line busted and sprayed oil on the exhaust. The resulting fire is something I want to avoid in the future. I bought an electronic gauge that came with a sending unit. It was a cheap gauge, so when it worked a few times and...

Thats a lot of what I was looking for. I have flow simulation software that I can use that will give me die steel temps after 20 cycles or so. It however doesnt take flow of water into consideration and will not tell me how much the temperature will elevate. Basically you just tell it what in...

Yes. One side of the block will have molten aluminum on it. 1280 degrees F. I am looking more for a simple if the block stayed at 500 degrees F and you constantly run water through it, what will the out temp change to. Will it end up steam on the out end or will it just be hotter water? what...

Hello all, I need to calculate water out temperature. What I know: Water Temperature in = 70 degrees F Size of drilled hole through a block = .242" diameter Pressure of water at inlet = 100 PSI Temperature of block = 500 degrees F Length of block = 5.542" Opening in opposite side of block is...

This is very helpful! We have been looking for an easy way to do this for a long time. Now, is there a way to do this where it will be associative? We have to enter projected area of a part, a feed runner, and a vacuum runner into a spread sheet for PQ^2 along with volumes of each. We always...
