Question

If the radius of the centrifugal pump impeller is reduced from 10 cm

Answer 1

$\huge\mathfrak\red{AnSweR}$

$head \: of \: number \: \frac{ {g}^{h} }{ {n}^{2} {d}^{2} } \: will \: remain \: constant \\ \\ \frac{ {h}^{2} }{ {n}^{2} {d}^{2} } = \frac{ {h}^{2} }{ {n}^{2} {d}^{2} } \\ \\ {h}^{2} = 8.1m$

Answer 2

AnSweR

\begin{lgathered}head \: of \: number \: \frac{ {g}^{h} }{ {n}^{2} {d}^{2} } \: will \: remain \: constant \\ \\ \frac{ {h}^{2} }{ {n}^{2} {d}^{2} } = \frac{ {h}^{2} }{ {n}^{2} {d}^{2} } \\ \\ {h}^{2} = 8.1m\end{lgathered}
