At what speed will the velocity of a stream of water be equal to 20 cm of mercury column? (Taking, g =10 ~ms ⁻² )

Step-by-step solution

Here, velocity head =20 ~cm of Hg =20 13.6 ~cm of water. As, velocity head = v^2 2 ~g 20 13.6= v ^2 2 1000 aligned v & = 20 13.6 2 1000 & =737.56 cms ⁻¹ & =7.3756 ~ms ⁻¹ aligned
