You need 1 CFM for every 30 BTU in a room.
How many CFM do I need per BTU?
To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.
How many CFM is a 80000 BTU furnace?
80,000 BTU 96% AFUE Variable Speed Goodman Gas Furnace 1600 CFM – Upflow/Horizontal.
How do you convert BTU to CFM?
Take the energy transfer rate in Btu and divide it by 100,000 to convert it to CFM. Take the result and add it up to 96.7. Divide that result by 60 to figure out the gas transfer rate.
How many CFM do I need for a 100000 BTU furnace?
How many cfm for 60,000 – 160,000 BTU furnace ? Furnace Capacity CFM (Airflow) How many CFM is a 60,000 BTU furnace? 1750 – 2000 CFM How many CFM is a 80,000 BTU furnace? 2320 – 2250 CFM How many CFM is a 100,000 BTU furnace? 2920 – 3325 CFM How many CFM is a 120,000 BTU furnace? 3500 – 4000 CFM.
How many CFM do I need to cool a room?
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 do I calculate CFM for air conditioner?
The calculation for CFM involves dividing the total volume of the space by the air exchange interval. To calculate room volume, you measure its length, width and height in feet and multiply these. Dividing this number by the change rate gives the required airflow in CFM.
How many cfm is a 60 000 BTU furnace?

What is the difference between BTU and CFM?
BTU describes the actual cooling power. CFM simply describes how fast it moves the working fluid (the air) through the system, and CFM does not matter for differences that small.
What is 1 CFM?
CFM is mainly used in measurement of ventilation engineering and industrial hygiene. It states the volumetric rate of flow of any gas or air in or out of a space. The higher the CFM coefficient, the more the amount of air or gas is being pushed through that space. 1 CFM is approximately 0.47 liter per second.
How many square feet will a 80000 BTU furnace heat?
80 X 1,000 square feet = 80,000 BTUs.
How many square feet will a 75000 BTU furnace heat?
A 75,000 BTU heater can heat a room of between 1,900 and 3,700 square feet in a cold climate if there is little to no insulation. In more temperate climates the heater fares better, heating an uninsulated room of any size from 2,400 to 4,600 square feet.
How many cfm is a 50000 BTU furnace?
Tempstar 50000 BTU Input 45500 BTU Output 92.1 % Multi-Position Single-Stage Condensing Gas Furnace, 1600 CFM.
How many CFM do I need for a 12×12 bathroom?
The rule of thumb is that you need at least 1 CFM per square foot of room area. To determine the square footage of your bathroom, multiply the length times the width.
What is good CFM for a ceiling fan?
Good CFM ranges from 4,000 to 5,000. Better ranges from 5,000 to 6,000. Best is over 6,000.
How often should air be changed in a room?
One way to measure ventilation is to figure out how often the air in a space is completely replaced. This is called Air Changes per Hour (ACH). In a 30-foot by 30-foot classroom that has 25 students in it, the air should be replaced at least every 15 minutes, which equals an ACH of 4.
What size duct do I need for a 12×12 room?
A 12×12 foot room will need a 4×8 inch supply duct to get an adequate CFM rate, which is about 144 CFM.
How many CFM is a 3 ton AC?
A 3-ton heat pump has approximately 1200 CFM of air flow.
How do I know the airflow of my AC?
Generally the edge of the filter is marked with an arrow which points in the direction of the airflow. In other words, the air travels from the tail of the arrow toward its point. If there is no arrow, the side that is stronger or reinforced by cardboard or wire mesh is the side the arrow should be pointing to.
How many cfm is 100 square feet?
Example: For residential bathrooms up to 100 sq. ft. in area, HVI recommends an exhaust rate of 1 cfm per square foot. A bathroom is 6′ to 10′ or 60 square feet.
How many cfm is a 75000 BTU furnace?
High Efficiency Upflow/Horizontal Blower with 1,785 Max CFM. Up to 4 Tons Cooling Capacity. 21″ Cabinet Width.
How many cfm is a 66000 BTU furnace?
66,000 BTU Furnace, 80% Efficiency, Single-Stage Burner, 800 CFM Multi-Speed Blower, Upflow / Horizontal Flow Application.
Why is 400 cfm a ton?
400 CFM per ton of air conditioning: The higher CFM is required to remove the sensible heat from the environment. However, if you have an environment that has high humidity then 350 CFM per ton is better. At the lower CFM the coil is colder and the air spends more time on the coil and increases dehumidification.
Who makes Goodman furnaces?
