- Two cylinders act right after one another. Each cylinder is metered, and some actions are slow, and there is a dwell between some actions. What is the minimum flow rate required (CFM) to operate this cylinders? (enter answer with 2 decimal places) Sequence of operations: Cyl. A extends with metering (takes 1.5 second) Dwell time for 2 seconds for part machining Cyl. B extend and retracts without metering (2 second) Dwell time for 10 seconds while an electric mixer is operated Cyl. A retracts quicky with no metering (0.5 seconds) Dwell time for 5 seconds while a part is placed before next cycle Assuming the displacements of the cylinders are: Cyl. A DE = 65 in3 Cyl.
