Differential Pressure Flowrate

This can be proven by plugging in the given values and solving the equation. The exit velocity of the entrained fluid (air) can then be calculated using the formula:Ve = Qe/Aewhere:Ve = exit velocity of entrained fluid (air)Qe = flow rate of entrained fluid (air) (calculated as 319 m3/sec)Ae = area of entrainment port (calculated as 7.07 m2, using the formula A = π*r^2, with r = 1.5 m)Therefore, the exit velocity of the entrained fluid (air) would be 45.11 m/s.

I am working on water aeration system that involves a water ejector.

With a inlet pressure of 1.31 Bar, flow rate is 12.3 m3/sec through a 1 meter (dia) nozzle. Exit velocity at nozzle is 16m/s with therefore pressure is 3500 Pascal.

What will be the flow rate and velocity of the entrained fluid (air) with pressure of 101325 Pascal if the entrainment port is 3 meter (dia)

My Answer: 319 m3/sec

Please advice if my answer is correct. Is there a formula to prove this.

The formula to calculate the flow rate of the entrained fluid (air) is:Qe = Qw * ((Pw/Pe)^0.5)where:Qe = flow rate of entrained fluid (air)Qw = flow rate of water (given as 12.3 m3/sec)Pw = pressure of water (given as 3500 Pascal)Pe = pressure of entrained fluid (air) (given as 101325 Pascal)Therefore, using the above formula, the flow rate of the entrained fluid (air) would be 319 m3/sec.
 

Related to Differential Pressure Flowrate

What is differential pressure flowrate?

Differential pressure flowrate is a measurement of the difference in pressure between two points in a fluid system. It is used to determine the flowrate of a fluid, such as air or water, through a pipe or other conduit.

How is differential pressure flowrate measured?

Differential pressure flowrate is typically measured using a device called a differential pressure flow meter, which has two pressure sensors positioned at different points in a fluid system. The difference in pressure between these two points is then used to calculate the flowrate.

What are the applications of differential pressure flowrate?

Differential pressure flowrate is commonly used in many industries, such as oil and gas, chemical processing, and water treatment. It can be used to measure the flow of liquids, gases, and steam in various systems.

What factors can affect differential pressure flowrate?

The accuracy of differential pressure flowrate measurements can be affected by factors such as temperature, fluid viscosity, and the condition of the flow meter. Changes in these factors can lead to errors in the calculated flowrate.

How can differential pressure flowrate be optimized?

To optimize differential pressure flowrate, it is important to ensure that the flow meter is properly calibrated and maintained. Additionally, factors such as pipe size, fluid properties, and flow conditions should be taken into account when selecting a flow meter and calculating flowrate.
