To find the suitable pipe size depending on the length, use the sizing information provided in the graphs or use the table on page 4. By trying various pipe sizes and making the total friction …

The result is a piping pressure loss of 1.1 inches of mercury per 100 feet. However, this calculation must be made in terms compatible with the chart or table for flow rate and pressure …

To find a specific value for a given piece of equipment with Figure 2, use the lowest expected condenser pressure at the minimum cooling- water temperature at the inlet (for barometric …

See Effective Pipe Length table for adjustments 3Above pipe size is what is typically at the intake to the vacuum system. Distribution piping may need to be larger.

Table of Allowable Total Equivalent Length for Vacuum System Exhaust Piping: NFPA99 SCFM with one pump in reserve (from cut sheet) Pipe Size (based on Sch 40, copper or brass)

•Vacuum Piping to be Type K or L Copper or Schedule 40 PVC per product specs and local code. • Main trunk lines must have a minimum slope of 1/4 inch per 10 feet towards the pump. • Use …

To determine the estimated pressure rise (∆P) for the selected pipe, find the intersection for the pipe size and the SCFM (or lbs./hr.) flow rate. This will usually be slightly different from the …
