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 Webzero the derivative of the specific energy, the magnitude of the critical depth can be determined as Figure 2. Specific energy diagram 3 2 g q yc = (5) The behavior of free-surface flows through a rectangular channel can be easily described using the specific energy diagram. It can be observed using the diagram in Figure 2 that if the

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.
