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.
