Head is the same in P and R pump (H) = 35 m can be connected in parallel to a common direct-current (DC) bus (Figure 1.9b). P and R are available for use in a pipe flow system and their head-discharge characteristics are as follows.įlow rate is the same in P and R pump (Q) = 0.3 cumecs This Handbook on Battery Energy Storage Systems is part of a series of. Thus, the first pump at capacity Q 1 develops the same head H as the second pump at capacity Q 2. Each pump develops the same head H at the corresponding capacity.The flow rate Q t (Q t = Q 1 + Q 2) is split between the inlet into Q 1 and Q 2. With pumps in parallel, the flow rates are additive with a common head. The purchase price of a traditional diaphragm pump is the smallest piece of the total. The purpose of this user manual and accompanying Microsoft Excel spreadsheet is to guide you through the basic process of designing a solar-powered water.When connected in series, the total head developed is H t = H 1 + H 2, where H 1, H 2 are the heads developed by the pump in series at the common flow rate Q.Since each pump generates a head H corresponding to a flow Q. In a series arrangement, each pump handles the same flow rate, but the total head produced by the combination of pumps will be additive.
