7. Cylinder ( ถังอากาศอัด ) เวลาการใช้งาน Example: for 4 liter/300 bar cylinder Total air capacity = Cylinder capacity x Cylinder pressure = 4 x 300 = 1200 liters of air Total duration of = Total air capacity / Average consumption cylinder = 1200 / 40 = 30 mins Working Duration = Total duration - Safety factor = 30 mins - 10 mins = 20 mins
8. Total air capacity = Cylinder capacity x Cylinder pressure = x = liters of air Total duration of = Total air capacity / Average consumption cylinder = / = mins Working Duration = Total duration - Safety factor = mins - 10 mins = mins Cylinder ( ถังอากาศอัด ) เวลาการใช้งาน Example: for 6.0 liter/ 300 bar cylinder 6.0 300 1,800 1,800 40 45 45 35
