(nominal diameter of valve ≤ nominal diameter of pipeline)– The kvs values for the desired nominal diameter can be found in the Belimodata sheets.2. 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.
