Subject: Skirt & Borderline cases Generally, there should be a margin of 1 to 3 feet between the calculated NPSH and the NPSH that should be made available. Borderline cases may create unexpected problems and additional costs that should be avoided whenever possible. If the calculated NPSH is adequate, note on the pump head sheet that the minimum skirt height is adequate.Мой предвар.вариант: |
