AI Thread Summary
SCFH, or Standard Cubic Feet per Hour, measures the volume of airflow adjusted for standard temperature and pressure. To convert SCFH to cubic meters per hour (m3/hr), it is important to recognize that SCFH translates to Nm3/hr, which accounts for normal conditions. The discussion highlights that higher pressure, such as 100 psi, increases the flow rate, resulting in a higher SCFM. Understanding these units is crucial for determining gas moles per hour and mass flow rates. Accurate conversion and comprehension of SCFH are essential for effective airflow calculations.

Hi.

What do we mean unit SCFH AIR ?
how can convert to m3/hr?
 
Engineering news on Phys.org
Standard Cubic Feet per Hour. Enough to get you started?

thanks a lot
 
Be aware:

That means it is the volume of air flow corrected to standard temperature and air pressure. Therefore, SCFH translates to Nm3/hr (Normal cubic meters per hour).

If you have 300 cfm of air at 100 psi, you've got a lot more SCFM.

The purpose of using these units is specifically so that you can determine the number of moles of gas per hour. Specifying SCFM is equivalent to specifying the mass flow rate.

Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
