I am currently studying gas pipe sizing calculations and am somewhat stumped by the flow rate.
Since the flow rate is based on m3/per hour, how is this established ? Is it based on the max output of the appliance per hour ?
Lets say I have a 30kW boiler running at max, this would convert to 2.84m3 of gas used per hour - Is this the correct flow rate for the appliance ?
Also, what if the boiler was range rated - lets say a 30kW heat only boiler was reduced to 10kW, would the pipe sizing still need to be for 30kW ?
