Specific speed for a centrifugal pump is
A
$$\frac{{{\text{N}}\sqrt {\text{Q}} }}{{{{\text{H}}^{\frac{3}{4}}}}}$$
B
$$\frac{{{\text{N}}\sqrt {\text{Q}} }}{{{{\text{H}}^{\frac{2}{3}}}}}$$
C
$$\frac{{{\text{N}}\sqrt {\text{Q}} }}{{{{\text{H}}^{\frac{1}{4}}}}}$$
D
$$\frac{{{\text{N}}\sqrt {\text{Q}} }}{{\text{H}}}$$
Correct Answer: $$\frac{{{\text{N}}\sqrt {\text{Q}} }}{{{{\text{H}}^{\frac{3}{4}}}}}$$
