PRESSURE
DROP
The pressure drop in a circuit (primary circuit or circuit for DHW) is determined using the graph below. To do this, you must calculate: 1. Number of streams = (Number of plates - 1)/2 The number of plates is indicated in the unit designation. (Example: MSC 429 = 29 plates, i.e. 14 streams) 2. Flow rate per stream = Total flow rate/Number of streams MSC 4 CURVE Pressure drop in mmWC
