Hello,
Here are few one liners from Hydraulics:
1. Open channel flow is in transitional stage when the Reynolds Number is from 500 to 2000.
2. In Pipe flow the flow is turbulent when the Reynolds Number is greater than 4000.
3. A semi- Circular open channel is the best hydraulic section among a circular, rectangular or square channel.
4. When the time of closure for a pressure moving with velocity v for a length of L is less than 2L/v, it is known as rapid closure.
4. A shooting flow is a steady and non-uniform flow.
5. Vena-contracta is the section having smallest cross section of the free flow from an orifice.
6. Co-efficient of discharge Cd= (Co-efficient of velocity)^2 * Co-efficient of contraction.
7. An equivalent pipe is a pipe which has same head loss and discharge as that of the original pipe.
8. If the hydraulic line at a junction is higher than the hydraulic lines at the Reservoir A and B and is lower than that at the reservoir C then, the water will flow from reservoir C to A and B.
9. The difference between two adjacent stream line functions at a section gives us the discharge per unit length.
10. Partial derivative of a stream line function w.r.t. the x and y will give us the velocities in the x and y direction at that point.
Thank you!
