Witrynaloading rate in determining the size of a restaurant’s drainfield. The major finding in this work is the identification of an upper limit for organic loading. The results suggested that the maximum organic loading rate lies between 1.5 and 2.4 lbs. BOD 5 per 1000 ft 2 per day. The recommended maximum loading rate for sands is 1.5 lbs. BOD 5 ... WitrynaWhat is the loading on each transformer? Using equations (5) and (6) on page 8, kVA. 1 = 348/(348 + 500) x 3500 = 1436 kVA kVA. 2 = 500/(348 + 500) x 3500 = 2064 kVA It can be seen by the example, because transformer percent impedances do not match, they cannot be loaded to there combined kVA rating. Load division between the …
