How do you calculate CFM of a pneumatic cylinder?

CFM = (A x S x EC) / 1728 + [(A – R) x S x RC] / 1728.
…
Air Flow Required for Double-Acting Cylinder
  1. A = Piston Area (Square Inches)
  2. S = Stroke (Inches)
  3. C = Cycles per Minute.
  4. CFM (Cubic Feet per Minute) = (A x S x C) / 1728.

How much air does a pneumatic cylinder use?

So, the consumption rate of a 2″ bore, 4″ stroke cylinder operating at 30 complete cycles per minute at 80 PSI is 2.81 SCFM (Standard Cubic Feet Per Minute) of free air.

How do you find the volume of air cylinder?

To find the volume of gas available from a compressed gas cylinder, we apply the Ideal Gas Law (PV = nRT). In a high-pressure cylinder, the volume will be affected by the content’s compressibility factor Z (PV = ZnRT). For example, an AL cylinder of pure helium may contain 134 cu.

How do you calculate air consumption?

Multiply the known flow by the ratio of the input pressures converted to absolute
  1. Step 1: Calculate the ratio of absolute inlet pressures. English Units: Metric Units: 80 PSIG + 14.7. = …
  2. Step 2: Multiply known flow by the above ratio you just calculated. English Units: Metric Units: 15 SCFM x 0.8256 = 12.384 SCFM.
