Measuring the pressure in a container without changing it
Perhaps you could use the expansion of the pressurized container to measure the internal pressure? …

How can I find inlet pressure of a valve by measuring the mass flow rate?
In principle, yes, you can calculate the inlet pressure of a valve by measuring the mass flow rate as it discharges to atmospheric conditions. … So, if you know what the Cv value is for a given valve, then you would be able to calculate the inlet pressure from the measured mass flow rate. …

When pressure is exerted on parallel hydraulic pistons, do they start extending at the same ...
Here, the cylinder pressure will increase relatively slowly. … The pressure will then continue to increase until the pressure required to lift the larger piston ($p_2$) is reached. …

Woodworking clamps, does force add up?
You seem to be confusing force and pressure. … The pressure from each clamp would reduce radially outwards from each clamping point, as you describe (although adding clamps will increase the average pressure acting across the entire length of the planks …

Is Pascal's law incorrect?
As stated in the comments, the pressure at B is (approximately) equal to atmospheric pressure, so Pascal's law holds. The pressure in the tube above B is lower than atmospheric ($p_a=p_b-\rho gh$). … The difference in pressure between the liquid and the atmosphere at A is compensated by the force of surface tension at the meniscus. …

Fluid flow around pipe, over end of pipe
Since the inner pipe has one end closed, there can't be any average flow velocity through it, which means there also can't be any pressure gradient along its length. … So, in a steady flow, I would expect there to be zero flow in the pipe and its pressure should equalize with the static pressure of the outer flow at its open end. …

Total and static pressure: which one is measured?
It depends on the direction of the orifice in the pressure measuring device, relative to the flow - either one can be measured. … This is because the measuring device blocks the flow and brings it to rest, thus converting the dynamic pressure into measurable static pressure (it is only static pressure that can actually be measured …

Where does air pressure come from?
In general, air pressure in the Earth's atmosphere is hydrostatic pressure, caused by the Earth's gravitational field. …

Is equation of continuity valid even against gravity?
So, if you have the same pressure drop as the horizontal case, the gravity term will act to increase $v$. Conversely, to achieve the same $v$, you wouldn't have to have as much of a pressure drop. … Gravity acts in a similar way to pressure on momentum. …

Shock waves at $M = 1$ and $M > 1$
I assume that here you are referring to a pressure wave travelling through a stationary gas? … I believe, if the wave is travelling faster than the upstream speed of sound, then it must be a shock, since no other type of pressure wave can travel faster than sound. …
