Flow rate in central heating system | DIYnot Forums

2009/12/28 · A 41kW boiler with a 20C differential required a flow rate of 41/ (4.2x20) =0.49 litres per second or 1.76 m³ per hour. If you are getting a temperature drop of 30C then the flow rate is 41/ (4.2x30) = 0.33 litres/ sec or 1.17m³ per hour. This graph shows how the flow rate (X axis) of the 25-55 varies with pressure (Y axis).

The mass flow rate of spray water to the first spray water group can be calculated along the same procedure: m& SHII + m& SPRAYII = m& SHIII (1) m& SHII ⋅ hSHII, 2 + m& SPRAYII ⋅ hSPRAY Figure 10 shows a flow chart with the symbols visualized of the boiler arrangement used in this calculation model.
