  2. How Do You Measure Static Pressure for Axial Flow Fan Efficiency?

    www.physicsforums.com/threads/how-do-you-measure-static-pressure-for-axial...

    Static pressure can be measured using a device called a manometer, which consists of a U-shaped tube filled with a liquid, such as water or mercury. The difference in height between the two sides of the U-tube is directly proportional to the static pressure being measured. 3.

  3. Introduction to Pitot-Static Systems in Gliders - Physics Forums

    The Pressure in the pitot (called dynamic pressure) varies with the speed of the aircraft relative to the air mass. We can add a second port that is oriented at nearly 90 degrees from the direction of motion. That is called a static port. A pitot-static tube has both the pitot port and the static port.

  4. Calculating Residual Pressure for Fixed Orifice Flow - Physics...

    Static Pressure is commonly measured in flowing systems. See the pitot tube. IMO this sentence should be corrected to "Total pressure = pressure that is measured when water is at rest. Under no-flow conditions, Static Pressure = Total Pressure"} So it seems to me that what you call residual pressure is exactly the same thing I call static pressure.

  5. Calculate water pressure coming out of a pipe - Physics Forums

    www.physicsforums.com/threads/calculate-water-pressure-coming-out-of-a-pipe.274737

    v1 = Q/A. Q = volume of water per sec. = m 3 /sec. A = Area of pipe opening. BTW: someone here said if you lower the diameter of the pipe, pressure gets higher. This always confuse me because according to Bernoulli's equation, if velocity is higher , pressure is lower. Lowering diameter increases velocity.

  6. Static Pressure in relation to CFM - Physics Forums

    www.physicsforums.com/threads/static-pressure-in-relation-to-cfm.807684

    Static pressure is the measure of the force per unit area exerted by a fluid on a surface at rest. In HVAC systems, it refers to the resistance to airflow caused by obstructions such as ductwork, filters, and coils.

  7. Static pressure vs. dynamic pressure - Physics Forums

    www.physicsforums.com/threads/static-pressure-vs-dynamic-pressure.169660

    Static pressure is the force exerted by a fluid on an object at rest, while dynamic pressure is the force exerted by a fluid in motion. Static pressure is measured perpendicular to the surface of the object, while dynamic pressure is measured parallel to the direction of fluid flow.

  8. How dynamic and static pressures are related - Physics Forums

    13. I teach aerodynamics and I’m looking for a way to explain how d and s pressure are related. I understand that as dynamic increases static decreases with the total sum remaining the same. With dynamic being zero the total goes to static. As dynamic increases the static pressure decreases.

  9. Pressure measurement using a Piezometer - Physics Forums

    www.physicsforums.com/threads/pressure-measurement-using-a-piezometer.933523

    A piezometer is a device used for measuring fluid pressure in a system. It consists of a small tube filled with a liquid (usually water) and a pressure sensor, such as a manometer or transducer. The height of the liquid in the tube changes in response to changes in pressure, allowing for accurate measurement. 2.

  10. Dynamic pressure in pressure units - Physics Forums

    www.physicsforums.com/threads/dynamic-pressure-in-pressure-units.1004758

    Dynamic pressure in pressure units. In summary, the conversation discussed the conversion of dynamic pressure into units used to measure static pressure. Dynamic pressure is defined as ½⋅density⋅velocity2 while pressure is defined as kg⋅m−1⋅s−2. However, both can be expressed in energy per volume and have the same units of kg⋅m ...

  11. Pitot Tubes and Static Pressure - Physics Forums

    www.physicsforums.com/threads/pitot-tubes-and-static-pressure.889617

    The question arises about how the top tube is able to measure static pressure when there is no airflow inside. It is explained that the pressure just outside the hole in the top is the static pressure at that point in the flow, and inside the hole, the pressure must be the same for there to be no flow, making it possible to measure the static ...
