piping rated for 250 PSI OWG
A tool that measures air pressure in a tire or going through a pipe is called an air pressure gauge.
when air is blown through the paper pipe, the velocity inside the pipe increases and according to Bernoulli's theory the pressure inside the pipe deceases. And the pipe squeezed.
2000 Psi
During prper winterization, the water in the bottom drain is usually "blown" out with compressed air. How this happens, is that a pipe with a schrader valve (the same type of valve on a ture intertube) is inserted into a pipe that is threaded into the pipe below the skimmer (with the leaf basket removed) An air compressor is then used to fill the tube with air. The air forces the water out of the entire pipe. Bubbles will come up from the drain when all of the water has been blown out of the pipe. The pressure of the air being in the pipe keeps the water from flowing back into the pipe. Hope this answers your question.
Because you have a leaky pipe joint or a bad pressure tank.
The air pressure inside a tornado is very low.
A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside, there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is less than the ambient air pressure), or the force will tend to straighten out the pipe (if the pressure is higher inside). This force can be measured, and from the measurement of this force, the gauge pressure within the pipe can be calculated.

it is the low pressure side
What type of condensate are you asking about? air conditioning
The answer is yes, if the pressure is below 150-160 psi.
In general any pressurized gas container is "empty" when the pressure inside is equal to ambient air pressure. There is still gas in the container, but not enough pressure to expell the gas. Medical oxygen tanks should never be allowed to go below 200psi. The tank is considered empty at this point and should be replaced.
