Application of specific energy and momentum function Coursework

Application of specific energy and momentum function - Coursework Example Conversely, the increase, in short, smooth step with the change in y within the channel and with the given upstream depth and corresponding discharge, y3 is increased. Y3 is increased due to the expansion and energy loss. A hydraulic jump is utilized for energy dissipation that occurs when the flows transitions from the supercritical to corresponding subcritical mainly due to the spillway and the steep slope to the mild slope. The depth of water downstream from the jump and the location of the jump are computed using the conservation of energy equation (Kiselev, Fomin & Vorozhtsov, 1999). It is expected from y1 that the depth of water to escalate as the specific energy of the prevailing reduces slowly. Moreover, the alternate depths at which the specific energies ought to be identical. Nevertheless, the values collected does not depict that as the underlying values were not adequate to produce the correct and expected graph thus the association was not represented as anticipated. The prevailing graphs derived from the depths of the flow, and corresponding specific energy at the section depicts that the depth escalates as the time elapses linearly with the specific energy indicating that the two underlying variables are linearly associated. The percentage relative head loss for the underlying theoretical outcomes is relatively higher than the corresponding practical percentage relative to the head loss. The difference is due to the depth of water subsequent to the hydraulic jump that was higher than that of the underlying experimental values. The energy is lost because of the turbulent flow implying that the real water depth is relatively lower than prevailing theoretical computations. The trend line depicts the positive correlation amidst the escalation of the Froude number and corresponding y3/y1 values. The experiment was undertaken under the controlled situations in order to
