Aikace-aikacen ka'idar kamanni na famfo
1. Lokacin da aka yi amfani da irin wannan doka a kan famfo fanfo guda ɗaya da ke gudana a cikin gudu daban-daban, ana iya samun shi:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2
Misali:
Akwai famfo, samfurin shine SLW50-200B, muna buƙatar canji SLW50-200B daga 50 Hz zuwa 60 Hz.
(daga 2960 zuwa 3552 rpm)
A 50 Hz, impeller yana da diamita na waje 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.
Don taƙaitawa, shugaban wannan nau'in famfo yakamata ya kai 52m a saurin 60Hz.
