Question

The height of a hydraulic jump in a stilling pool was found to be 10 cm in a model with $L_p/L_m=36$. The prototype jump height would be

• A. 3.6 m
• B. 21.6 m
• C. 0.6 m
• D. Indeterminable for want of adequate data

Answer 1

The correct option is A 3.6 m

$\frac{L_p}{L_m}=36$

$\therefore$ Height of jump in prototype

$=36\times 10=360cm=3.6m$
