1. Lokacin da ake amfani da dokar irin wannan dokar ta vane ɗaya ta vane yana gudana a hanyoyi daban-daban, ana iya samu:
• Q1 / Q2 = N1 / N2
• H1 / H2 = (N1 / N2) 2
• P1 / P2 = (N1 / N2) 3
• NPSH1 / NPSH2 = (N1 / N2) 2
Misali:
Kasancewa na famfo, samfurin shine slw50-200b, muna buƙatar canji slw50-200b daga 50 na HZ zuwa 60 hz.
(daga 2960 rpm zuwa 3552 rpm)
A 50 HZ, mai impeller yana da m diamita na 165 mm da shugaban 36 m.
H60hz / h50hz = (n60hz / n50hz) ² = (3552/2960) 2 = (1.2) ² = 1.44
A 60 hz, h60hz = 36 × 1.44 = 51.84m.
A taƙaice, shugaban wannan nau'in famfo ya kamata ya kai 52m a saurin saurin.
