In pneumatic pump air consumption is referred to as 50CFM. What is CFM in this contex referred to?
1150 cfm is typical of a 3-ton cooling system, based on 400 cfm per ton. THere are many more questions to ask to give you the answer you request. A lot depends on your specific configuration and what this is being used for.
To convert cmh to cfm ..... divide cmh by 1.7 to convert into cfm....
The recommended CFM rating for a range hood depends on the size and layout of your kitchen. As a general guideline, aim for a minimum of 100 CFM per linear foot of your range. For example, if your range is 30 inches wide, you would want a range hood with at least 250 CFM. However, for larger kitchens or kitchens with high ceilings, you may need a higher CFM rating. It's best to consult with a professional to determine the most suitable CFM rating for your specific kitchen.
Tr = cfm/400
750 CFM
CFM (cubic feet per minute) is not directly related to horsepower unless a pressure is given with the CFM number. A 1 HP pump might only generate 2.5 CFM at 100 PSI, for example. That same 1 HP can push hundreds of CFM at standard air pressure (a large fan, for example).
1tr = 400 cfm
5-10 cfm = -5
CFM International was created in 1974.
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.
A high CFM (cubic feet per minute) rating indicates greater airflow, which can be beneficial for applications requiring efficient ventilation, cooling, or drying. However, whether a high CFM is better depends on the specific needs of the task; for example, a low CFM may be more suitable for quieter operations or precise airflow control. Ultimately, the best choice depends on the intended use and the balance between airflow, noise levels, and energy efficiency.
CFM is a really in depth subject. With that question you are at the point where you should be looking in to some books; there are good hvac books available threw Amazon .com and some local book stores .
