Artificial Recharge of Groundwater Read More. January 6, at am. There are five slope classifications designated by the letters C, M , S, A, and H critical, mild, steep, adverse, and horizontal respectively.

The profile is further classified according to the relative position of the actual flow depth to normal and critical depth as designated by the numbers 1, 2, and 3.

Type 1 curve: Actual depth is greater than y c and y n , flow is subcritical. Type 2 curve: actual depth is between y c and y n , flow can be either subcritical or supercritical. Type 3 curve: actual depth is less than both y c and y n , flow is supercritical. Note: While water surface profiles are influenced by the channel slope, flow profiles are also classified by the water surface slope. When the flow is uniform and steady these slopes are the same.

This means that the various layers of liquid flow without turbulence in the form of laminations. It is also found that a flow in a pipe is laminar if the Reynolds Number based on diameter of the pipe is less than and is turbulent if it is greater than Begin typing your search term above and press enter to search.

What is bed slope? Notation Our calculation allows you to use a variety of units with all of the conversions computed internally. The units shown below are SI international system of units. These are input checks. Input diameter and flow rate must be positive numbers. D must be between 10 -6 m and m.

Run-time error. The combination of flow rate and diameter that were input result in a very small critical depth approaching machine precision. The combination of flow rate and diameter that were input result in critical depth greater than the pipe diameter.
