Depth of discharge formula
WebWe know that for a given discharge per unit width of a channel, for a given value of the specific energy head E there can be two possible depths of flow d 1 and d 2. For instance corresponding to specific energy head E = OG [Fig. 14.82], the depth of … WebThe depth of discharge is the amount of a battery’s storage capacity that is utilized. For example, a battery that is discharged only by 20% of its full energy capacity has a much greater cycle life than a battery that is discharged more deeply by 80% of its capacity so that only 20% of its full energy charge remains.
