Can anyone direct me to a table or calculation regarding flow of water, impelled only by gravity, through a pipe or channel?
I would like to determine the nominal flow rate of water flowing through a 1" (I.D.) pipe, with no other pressure than just gravity. The vertical drop from the tank is...
I have an old hand tool that utilizes a universal motor that has failed, and there is a three-terminal device on the board in the tool that I have never seen before. It is where the problem likely lies (there is smoke residue around the device) There are no markings, orientation dots or any...
Hi, I thought this might be the best place to begin my quest. We have an electrical room in a waste-water facility that stays relatively clean and dry- yet quite often (monthly) there is a growth of a white, almost calcium looking, substance that covers all the terminals that are common with the...
We have two identical hydraulic systems on a production line. One hydraulic valve coil fails daily (or even more often). The systems are the same electrically. My question is can excessive stiction in the valve or unusual forces in the mechanical system create this problem?
I realize that this may be a simple question but...
In a open (Not actually open but not pressurized or blanketed) tank of water heated to 150 deg. F, air is around 120 degrees F in the spaces above the top of the tank, There is a exhaust fan drawing 5200 scfm from the around the top of the...
About once a month a QA200 fuse clears on the utility riser at our plant. There has been no indication as to why it blows. We have a 2000 KVA 12470-> 480volt transformer. On the load (480v)side beyond the main CB there is a fixed bank of 400 KVar caps installed. We have had no indication of...
I have a parts washer system that uses a vertical centrifugal pump to deliver a heated, 97% water solution up to the top of the washer through a 3” pipe, then distributes (branches) into two 3” pipes. One of these pipe branches delivers water to 21 nozzles, with an equivalent orifice size of...
Hi,
Does anyone know of a sensor or system that can verify if a hole is threaded? This is for poke-yoke purposes and the system or sensor needs to be adjustable or programmable for different parts/configuarations if possible.
Thanks

Hi, Can anyone direct me to a manufacturer of a magnet controller for an electromagnetic chuck in a surface grinder? The magnet is rated for 225Vdc and 10 amps. I would like to be able to adjust magnetism from an analog output of a PLC. I will also need to be aable to demag. with the same...

I know a company owner whose automation guy left the company after password protecting a fairly wide base of PLCs in customer locations (He also has all sourcecode). He refuses to divulge the passwords or return the sourcecode and the situation has gone to litigation. In the meantime there is a...
