How many CFM is my furnace?
To find required airflow divide the rated furnace input by 10,000 Btu. 100,000 divided by 10,000 equals a factor of 10. 10 Times 130 cfm equals 1300 cfm. This airflow rule is applied to determine furnace airflow for three types of furnaces.
How many CFM do I need for heating?
AIRFLOW. Air quantities (cfm): 400 cfm per ton of cooling is needed for normal comfort applications, 500 cfm per ton of cooling for heat pump and high sensible heat applications, and 350 cfm per ton of cooling for high latent heat applications.
How many CFM is a 50000 BTU furnace?

How much is a 60 000 BTU furnace?
Natural Gas Heating System Prices by BTU
| Furnace Size (BTU) | Typical Furnace Cost with Installation* |
|---|---|
| 50,000 | $2,300 – $3,800 |
| 60,000 | $2,500 – $4,200 |
| 75,000 | $2,700 – $4,600 |
| 80,000 | $3,000 – $4,900 |
How many CFM do I need per BTU?
To determine the CFM of a hood over a gas range, add up the BTU output of each burner and divide it by 100. For example, if you have two burners that put out 10,000 BTUs each and two burners that put out 15,000 BTUs each, your total BTUs for your stovetop would be 50,000. 50,000 divided by 100 equals 500 CFM.
How many CFM is a 12 inch round duct?
CFM Sizing Chart For Flex Round Ducts (50-1,700 CFM)
| Duct Size (Inches) | Flex Duct Airflow (CFM) |
|---|---|
| 10 inches | 300 CFM |
| 12 inches | 480 CFM |
| 14 inches | 700 CFM |
| 16 inches | 1,000 CFM |
How many CFM can a 4 duct handle?
Reviewing the chart, a 4” pipe will convey 395 CFM at 4500 FPM. This means that a 4” pick-up on a machine will use 395 CFM from the filtering system; or, if you know that a machine will require approximately 400 CFM to remove the waste, you should use a 4” pipe for that purpose.
Is round or square duct better?
In many ways, round metal duct work is more economical than rectangular metal duct work as a means of conveying air. 1) Size: For a given pressure loss, the surface area of rectangular duct can be double the comparable round duct surface area. 3) Efficiency: Using round duct achieves a better-sealed system.
How do you calculate CFM for a room?
How to Calculate the CFM of a Room
- Measure the room’s width and length.
- Multiply the three measurements from step 1 to determine the cubic footage of the room.
- Multiply the cubic volume of the room by the number of times you want the air to turn over or exchange in an hour.
