I believe it is experiment on Bernoulli's principle that use conservation of energy to calculate velocity or flow of the incompressible fluid.
It is stated
Total Pressure = static Pressure at reference height + momentum + potential height
See attachment for experiment detail.
A pitot tube uses Bernoulli's equation to measure fluid flow velocity by comparing the pressure difference between the stagnation point and the dynamic pressure of the fluid. This difference in pressure is used to calculate the velocity of the fluid flowing past the pitot tube.
it depends on what your dealing with, room pressure is found with a barometer, to measure pressure in a flowing fluid, you can use a manometer. there are many variou ways to find pressure, but you must be specific on the circumstances
The property of flowing very quickly in liquid is called fluidity. It refers to the measure of the extent to which a substance is fluid.
Fluid speed and fluid pressure are inversely related according to Bernoulli's principle. As fluid speed increases, fluid pressure decreases, and vice versa. This means that in a flowing fluid, areas of high speed will have lower pressure, and areas of low speed will have higher pressure.
the pressure whose pressure is to be calculated is flowing agaunst gravity
Bernoulli's principle states that the pressure exerted by a moving stream of fluid is less than the pressure of the surrounding fluid. This principle describes the relationship between fluid velocity and pressure in a flowing fluid system.
Due to friction between the fluid and the walls of the pipe, pressure increases within the pipe.

1: the pressure on a surface at which a flowing fluid is brought to rest in excess of the pressure on it when the fluid is not flowing2: the quantity of air measured by most airspeed instruments and equal to the product 1⁄2 ρV2 where ρ is the density of the air and V is the relative speed of the air
A manometer is used to measure pressure. It typically consists of a U-shaped tube filled with fluid that responds to changes in pressure by moving the fluid levels.
velocity is a distance travelled per sec
Orifice meter measures pressure by forcing fluid through a restriction (orifice plate) in the pipeline, causing a pressure drop. This pressure drop is proportional to the flow rate, which can be used to determine the pressure of the fluid. By measuring this pressure drop, the orifice meter can indirectly measure the pressure of the fluid in the pipeline.
