Friction Factor: The Small Coefficient Driving Pressure Drop
If you want to size a pipe or duct accurately, you must calculate the friction factor: a technical, iterative process with multiple variables (Re, material, diameter, temperature). This guide explains the methods and shows you how to apply them, so your pressure drop calculations are always precise.

For decades, engineers have relied on the simple summation of room heat losses to size systems. However, BS EN 12831-1:2017 turns this linear logic on its head by introducing the concept of diversity. Moving beyond simple summation is now essential, as over-sizing introduces a serious risk of inefficiency that compromises modern heat pump performance.

Your radiators work fine today, but will the lower temperature of a heat pump cause too much pressure drop through those narrow microbore pipes tomorrow?
