Time and time related variables in engineering

Time is the event progression starting from past to present and then, future statistically. The time-related variable is any particular value in relation to time to assess its changes on a specified (XY) plane.

The trapezoidal channel below must maintain a discharge of Q = 20 x SN (m3/s). You may assume that the channel slope is negligible. Use MS Excel spreadsheet to plot the specific energy curve and determine the critical depth Dc. Hint: You should first set up a column of normal depth D (m) ranging from 0 to SN, and then calculate the area (A), velocity (V), energy (E) and Froude number (Fr). ***SN=21
