How do you calculate ventilation needed in a room? Divide the volume of the room by the fan's flow rate, using the same unit system. The volume unit will cancel out, leaving only the time unit. The number achieved here is the time it takes for the air in the space to be replaced ...
If you need to, you can calculate velocity from pressure in these problems if you are given enough information. Pressure differentials between locations are one means by which air is compelled to move from place to place, and the higher the pressure, the higher the flow rate of air. Pressure...
The value that expresses this combined noise is found by determining the energy of the noise and then using it to calculate the increase in sound pressure. The relationship between sound energy (J) and sound pressure (P) is expressed in the following formula: Using the above formula, the ...
Often, inappropriate uses consume significant amounts of flow, and savings can be gained if the operation can be supplied more efficiently through optimization measures. To be able to initiate improvement projects, we must first calculate how much air we are wasting. When we know the answer we ...
The basic formula to calculate the pump flow rate is: Flow Rate (Q) = Area (A) × Velocity (V) Where: Qis the flow rate Ais the cross-sectional area of the pipe or channel Vis the velocity of the fluid This formula is the foundation for more complex calculations and adjustments that...
I know the mass flow rate of the mixture. I need to get the velocity of the mixture. What is the density of the mixture. How do i calculate density in order to calculate the velocity.January 13, 2003, 09:53 Re: how to calculate two phase flow density #2 cfd Guest Posts: n/...

To maintain healthy airflow for your compressed air system, the proper pipe size is needed. Learn how to properly calculate the correct pipe size.
If you want to calculate the flow rate of water or air in cubic feet per second, you need to measure the cross-sectional area of the pipe or duct in feet and measure the velocity of the water or air in feet per second, then use Q = A×v. For pressurized
Estimate the volumetric flow rate using an orifice calculation. Assume that the upstream pipe diameter is the ID of the 3" pipe for d/D. Calculate the volumetric flow rate. Convert to a mass flow rate using the conditions of the gas in the pipe. This can be done at a few pressures si...
