General notes for project planning / Dimensioning steps for standard control valves2. Determining volumetric flow V'1002. Determining volumetric flow V'100If the thermal output of a consumer and the associated differential temperature between the supply and return lines are known, then the following formula can be used to calculate the volumetric flow. The density and thermal capacity of the water are taken into account as constant values by a factor of 0.86.V'100 = 0.86 .Q100 ∆TV'100 : [m3/h] Q100 : [kW] : [k] ∆T3. Calculate kv valueOnce the volumetric flow has been calculated, the flow factor kv can be deter- mined for a differential pressure of 100 kPa.kv =V'100∆pv100 100∆pv100 : [kPa] : [m3/h] V'100 : [m3/h] kv4.
