Question: Receivers are pressure vessels, and their cost reflects this rating. They need to be large enough to meet the performance criteria, but cost considerations dictate that they be no larger than necessary. A manufacturing operation uses an estimated 1000 cfm. On-off control of the compressor is used, and cycling less than once every four minutes is undesirable. Pressure can drop from 105 to 95 psi before the compressor cycles back on.
1. What size (ft3) receiver is needed?
2. If the pressure can drop 15 psi before the compressor cycles on, what size receiver is needed?
