Lohm Laws for Liquids – How to Combine Flow Resistances for Liquids

For parallel flow, the total Lohm rating is:


Please note that this relationship is identical to the electrical equation for Ohms.

For Series Flow, the total Lohm rating is:



Please note that this relationship is not the same as in electrical problems. The difference is due to the non-linearity of I and H:
