At what speed will the velocity  head of a stream of water be  equal to 20 cm of mercury  column? Take g = 10m/s²

$\huge\mathcal{\fcolorbox{cyan}{black}{\pink{Answer}}}$

According to the question,

Potential energy head = sgh

Velocity head = 1/2 sv²

So, 1/2 sv² = sgh

1/2 (1) v² = (13.6) (10⁴) (20) (10⁻²)

v² = (136000) (10) (20) (2) (10⁻²)

v² = √544000

v = 544000

v = 737.56 m/s
