How do you calculate the tonnage of AHU?
You need 350 to 400 cfm per ton (12,000 btu) of cooling. So, divide your cfm by 400. For example, a 1200 cfm blower on an air handler could handler up to 3 tons. All calculations depend on your duct being the proper size for the equipment.

What is relation between cfm and cmh?
The relationship between cubic feet per minute or cfm and cubic meter per hour or cmh is that there are approximately 0.59 cfm in 1 cmh. Similarly, 1 cfm is equal to approximately 1.7 cmh.
How many cfm of air equals 1 ton of air?
There are 400 cfm in 1 ton
What is the formula for calculating cfm?
Take the number of cubic feet and divide that by the number of minutes. cfm=cf/m

How do you calculate the weight of AHU?
To calculate the weight of an Air Handling Unit (AHU), you would need to know the dimensions and materials used in its construction. Multiply the volume of the AHU by the density of the materials to determine its weight. Additionally, you can refer to the manufacturer's specifications for the AHU's weight.

How do you get cfm with a manometer?
To calculate CFM (cubic feet per minute) using a manometer, measure the pressure difference across a restriction in the airflow system. Use the manometer reading and the area of the restriction to determine the velocity pressure. Then, use the velocity pressure to calculate the airflow in CFM using the formula CFM = (Velocity Pressure * Area of the Restriction) / 4005.
How do you calculate horse power of compressor?
To calculate the horse power of a compressor one would need to use the following calculation. Pump ratio x GPM @ 100 psi = CFM. For a gas compressor divide CFM by 2 and for an electric compressor, divide CFM by 4. GPM is gallons per minute and CFM is air consumption in cubic feet per minute.
How do you calculate sensible heat if you know cfm and temperature difference?
To calculate sensible heat, you can use the formula: Sensible Heat (BTU/hr) = 1.08 x CFM x Temperature Difference (°F). Just multiply the CFM value by 1.08 and then by the temperature difference in Fahrenheit to get the sensible heat in BTU per hour.
