To solve the problem, we need to find the velocity of flow in a stream of water given that the velocity head is equal to 20 cm of mercury column. We will also use the relative density of mercury and the acceleration due to gravity. ### Step-by-Step Solution: 1. **Understand the given data:** - Velocity head (h) = 20 cm of mercury (Hg) - Relative density of mercury = 13.6 - Acceleration due to gravity (g) = 9.8 m/s² ...
