Specific energy hydraulics
WebMar 5, 2024 · Ho, also called the specific energy, is simply the head (i.e., flow energy per unit weight) relative to the channel bottom. Using Ho, Equation 5.4.4 becomes Ho2 + ho2 = … Web7.4.2 Specific Energy Specific energy, E, is defined as the energy head relative to the channel bottom. If the channel is not too steep (slope less than 10%) and the streamlines are nearly straight and parallel (so that the hydrostatic assumption holds), the specific energy E becomes the sum of the depth and velocity head: E = y + α (V2/2g) (7.1)

WebApr 14, 2024 · There already is a concept of “specific energy” in hydraulics which has been in use much longer than specific energy in pumping. It refers to whether the energy in … WebSep 21, 2008 · Drilling Specific Energy (DSE) is the amount of energy required to destroy and remove underneath the bit a unit volume of rock. DSE includes axial, torsional and hydraulic energy. DSE is different than MSE because it includes a hydraulic term. The initial MSE correlation (Teale, 1964) has been modified to accommodate the new hydraulic term.
WebMar 13, 2013 · Specific energy at a particular section is defined as The total head with respect to the bed of the channel. Or The total head at a cross section by taking the datum passing through the bed of section at that … WebCritical depth occurs when the flow in a channel has a minimum specific energy.Specific energy refers to the sum of the depth of flow and the velocity head. Critical depth depends on the channel shape and flow rate. The depth of flow at the culvert outlet is assumed to be equal to critical depth for culverts operating under outlet control with low tailwater.
Websecond term in equation (4) (kinetic energy) is large. At some intermediate depth of flow the specific energy has a minimum value. The value of y which gives a minimum specific energy is called the critical depth. From the table and graph below, it can be seen that the critical depth is 1.5 ft to 2 significant figures WebThe critical hydraulic mean depth, h cm, is the depth at which total specific energy is minimum for a given discharge. Conversely, h cm is the depth at which the discharge is maximum for a given total specific energy. When depth is greater than critical, the resulting velocity is considered streaming or tranquil and is called subcritical velocity.
