This pipe holds about 19.63 litres (5.19 US gallons) of liquid.

  • Volume is the cross-section area of the bore (π × radius²) multiplied by the pipe length.
  • Filled with water it weighs roughly 19.6 kg (43.2 lb), useful for sizing supports and pumps.
  • Make sure the diameter is the inner bore in millimetres, since wall thickness reduces capacity.

Next stepFor a different fluid, set its density in the Liquid options and the weight, cost and velocity all update.
