The CFM of the equipment are given, how to calculate Static Pressure for it.
have a AC unit that is rated 5,200 CFM's. What is the conversion to BTU's
25.65
CFM is a unit of flow PSI is a unit of pressure you cant equate these except to say that they are inversely proportional... as pressure increases flow decreases
PSIG has nothing to do with CFM. Ratings for a/c units and heat pumps are generally 400 cfm/ ton of capacity. 12,000 Btuh is one ton of refrigeration. So if the a/c unit is 6000 btuh, it would be a half ton unit.
2000 cfm. 400 a ton.
Internal Static Pressure, as it pertains to HVAC AHU's: it is the static pressure losses, which the fan needs to overcome to create a certain amount of CFM flow through the unit. It may or may not include those losses created by the filter boxes, dampers, louvers, etc. All other static pressure losses not considered internal can be notes as ESP (External Static Pressure). The absolute value of the sum of the ESP and ISP is referred to as Total Static Pressure (TSP), which is the pressure that the fan will have to overcome to generate the rated CFM.
The term cfm stands for cubic feet per minute. It is a unit of measurement used to determine the amount of air flow,.
cubic feet per minute...
1tr = 400 cfm
When you are talking you send your sound pressure, but around you is the atmospheric pressure and your waves are on top of that. You are changing a bit but not noticable that nearly static air pressure. http://en.wikipedia.org/wiki/Atmospheric_pressure
Check the air flow per cubic meter of your diffuser area cover in your unit. CFM= cubic feet per minutes.
