Question

At what speed will the velocity head of stream of water be 40cm?

Answer 1

Answer:

h = 40cm = 0.4m − head mercury column; Velocity head = 40cm of Hg column hw = h ∙ 13.6 cm of water column.

Answer 2

Explanation:

= 40cm = 0.4m − head mercury column; Velocity head = 40cm of Hg column hw = h ∙ 13.6 cm of water column
