Which is the biggest dam of world?
Three Gorges Dam
Three Gorges Dam, China is the world's largest hydroelectric facility. In 2012, the Three Gorges Dam in China took over the #1 spot of the largest hydroelectric dam (in electricity production), replacing the Itaipú hydroelectric power plant in Brazil and Paraguay.
Which is the longest dam in India?
Hirakud Dam
Hidden Worlds And Stories Of Progress At Hirakud Dam, Odisha. Hirakud is the longest earthen Dam in the world and stands across the mighty river, Mahanadi, in the Sambalpur region of Odisha. It was the first major multipurpose river valley project after India's Independence in 1947.

Hydraulic jump practical part-1 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 that 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.

hydraulic jump A hydraulic jump is a phenomenon in the science of hydraulics that 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. What causes a hydraulic jump? A hydraulic jump occurs when the upstream flow is supercritical (F>1). To have a jump , there must be a flow impediment downstream. The downstream impediment could be a weir, a bridge abutment, a dam, or simply channel friction. Water depth increases during a hydraulic jump and energy is dissipated as turbulence. How do you calculate hydraulic jump? How do you calculate hydraulic jump? Equations for Hydraulic Jump Calculations y2/y1 = (1/2)[-1 + (1 + 8Fr12)1/2] ; V1 = Q/(by1) ; and Fr1 = V1/(y1g)1/2. The upstream velocity, V1 and upstream Froude number, Fr1, need to be calculated first, using the last two equations, then the downstream depth of flow, y2 can be calcula
The demonstration of a hydraulic jump in rectangular open channel part- 2 !! Fluid mechanics -2 What is the hydraulic jump and its use? Industrial. The hydraulic jump is the most commonly used choice of design engineers for energy dissipation below spillways and outlets. A properly designed hydraulic jump can provide for 60-70% energy dissipation of the energy in the basin itself, limiting the damage to structures and the streambed. Types of Hydraulic Jumps – Undular Hydraulic Jump – Weak Jump – Oscillating Hydraulic Jump – Steady Hydraulic Jump – Strong Hydraulic Jump – What does Froude's number mean? The Froude number is a measurement of bulk flow characteristics such as waves, sand bedforms, flow/depth interactions at a cross-section or between boulders. The denominator represents the speed of a small wave on the water surface relative to the speed of the water, called wave celerity. What is the length of a hydraulic jump? In civil engineering, the hydraulic jump is us
