WebApr 14, 2024 · Where S = specific energy which has units of power per flow-head. If you combine equations (1) and (2), you get. S = k/e (3) So specific energy, if you cancel the units, is just the inverse of efficiency. It is one if the pump is perfectly efficient and increases as the pump becomes less efficient. Both metrics are correct and useful. 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. parallelfalzartenWebsecond 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.

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. Webspecific energy above a certain minimum value (e.g., H3 = H4 in Figure 2), two alternate depths are possible, one corresponding to a subcritical flow (y3) and the other to a …
