When a fluid flowing through a pipe encounters a constriction, the increase in the speed of flow means that there is a momentary low pressure created at this point. The pressure at other regions of the pipe is much higher. Due to this pressure difference, fluid rushes to the constriction from other parts of the pipe.

Orifice plates constrict fluid flow to produce differential pressure across a flat piece of metal that contains a bored hole. Cone-based devices position a cone in the center of a fluid flow to create a differential pressure that is proportional to velocity. Pitot tubes are pairs of hollow tubes.

fan airflow-pressure curve. Oversized fans generate excess flow energy, resulting in high airflow noise and increased stress on the fan and the system. Consequently, oversized fans not only cost more to purchase and to operate, they create avoidable system performance problems. The use of a "systems approach" in the fan selection process

Solution The pressure in a tank is measured with a manometer by measuring the differential height of the manometer fluid. The absolute pressure in the tank is to be determined for two cases: the manometer arm with the (a) higher and (b) lower fluid level being attached to the tank. Assumptions The fluid in the manometer is incompressible.

The velocity at face i is taken to be V~ i = uiˆi + vi ˆj. Applying the mass conservation equation (5) to the control volume defined by the cell gives −u1∆y −v2∆x+u3∆y +v4∆x = 0 This is the discrete form of the continuity equation for the cell.

Accordingly, the differential piston remains in the left-hand position shown, with the result that the valve chamber 47 is filled with fluid under pressure, while valve chamber 43 is connected to the exhaust. This means that there is fluid under pressure in the part 50 of the external cylinder 42, while the space 41 is connected to v 4 the exhaust.

In general, pressure is a measure of the force exerted per unit area on the boundaries of a substance.The term dynamic pressure (sometimes called velocity pressure) is associated with fluid flow and with the Bernoulli's effect, which is described by the Bernoulli's equation:. This effect causes the lowering of fluid pressure (static pressure) in regions where the flow velocity is increased.

To calculate pressure drop, the difference between the pressure of the gas when it enters the instrument and the pressure of the gas when it leaves the instrument is noted (Figure 1).
