Hydraulic jump practical

This video tells about how to produce the hydraulic jump in an open channel and to calculate the loss of energy due to the creation of the hydraulic jump. standing wave. Loss of Kinetic Energy. The velocity of subcritical flow is less than supercritical flow. The depth of subcritical flow is greater than the depth of supercritical flow. Calculation part For discharge= Q= volume/time Q= A * V Q= b * Y1 * V1 Q= b * Y2 * V2 Fr1 = V/ root ( g*y1) loss of enenrgy= (y2-y1)^3 ------------- 4y1*y2 A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways. When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise occurs in the liquid surface. Types of Hydraulic Jumps – Based on Froude's Number: Undular Hydraulic Jump – Froude Number (1 to 3): ... Weak Jump – Froude Number (3 to 6) ... Oscillating Hydraulic Jump – Froude Number (6-20) ... Steady Hydraulic Jump – Froude Number (20 to 80) ... Strong Hydraulic Jump – Froude Number (greater than 80)
