The nomogram shown here can be used to calculate the pressure loss caused by reducers and
expanders:
• Calculate the ratio of the diameters d/D.
• From the nomogram read off the pressure loss as a function of flow velocity (downstream from
the reduction) and the d/D ratio.
• The nomogram only applies to liquids with a viscosity similar to that of water.
• If the medium has a high viscosity, a larger measuring tube diameter can be considered in
order to reduce pressure loss.
