In Figure 7 the observed cumulative frequencies are compared with the mixed distribution (continuous line), for which the not null water request was described by means of the L distribution (Equation (7)). The parameters of the distribution were estimated on the basis of experimental data and the relative values are reported in Table 3 (columns , and ). The plots with dot lines in Figure 7 furthermore represent the MD CDFs, where Equation (5) gave the probability of null request (in Table 3, column ) and the standard deviations (in Table 3, column ) has been estimated by means of the relation (Equation (8)) described in the following section.
