WebbTo be able to do theoretical probabilities, there is an assumption that you need to consider. It is that all of the outcomes in the sample space need to be equally likely outcomes. This means that every outcome of the experiment needs to have the same chance of happening. Example 4.2. 1 Equally likely outcomes Webb2 nov. 2010 · S. Ge, in Encyclopedia of Atmospheric Sciences, 2003 Hydraulic Head. Hydraulic head is one of the key parameters describing the mechanical energy state of a hydraulic system. It represents the mechanical energy per unit weight of the fluid in the system. Hydraulic head is defined as h = h p + h z, where h is the hydraulic head, h p is …
