Calculating absolute pressure with a U-tube manometer requires filling it with a non-volatile fluid and sealing one end. The non-sealed end is exposed to whatever fluid you wish to measure the pressure of. The difference in the height of the manometer fluid between the open arm and the sealed arm is an indication of absolute pressure. At zero absolute pressure the fluid should be at the same height in both arms with vacuum above the fluid in the sealed arm. From a practical standpoint, there are no fluids that have zero vapor pressure, but fluids are available with vapor pressures low enough to be negligible compared to the limitations of the ability of the person reading the measurements to read the height of the fluid. As an example, under most operating conditions Mercury has a negligible vapor pressure. If you start getting up to high temperatures, however, all bets are off.

How do you see electricity?
you cant see it its the same with the current. Electric current or the movement of electrons can be made visible with the use of a simple LED. Led's are transducers of current into light. When a current passes through an LED, its passage stimulates photon emission through a process of recombination. A novel device that exploits this fact is called INDI-LINK and will render a current over the range of 3mA to 10 Amp AC or DC into a readable signal of current presence and polarity. Add to this the fact that anything electric that is working properly must use current, when and INDI-LINK device is included in the circuit, the circuit becomes operationally transparent to the Human eye and greatly assists the operator in commissioning, testing and proving any electrical system. Checkout INDI-LINK on utube for more info.
I can not get access to utube the utube downloader's virus prevents me if I type the full of utube the virus strucs me with 'utube is banned' and closes the windowhow can I delete that utube preventer?
you can't take the block off unless you reset all the MEMERY on the memery stick. But that is hard so get a computer wiz to help you. Now if you don't mind I have to party.
