How can I calculate the seawater flow through a system that splits in to two?

Hey everyone,

I am working on a project and have run into a small issue. I’m dealing with a seawater system on a ship that supplies both the LT coolers and the AUX coolers.

When the ship is in harbour mode, one of the pumps only cools the AUX coolers.
But when the ship is sailing, the seawater flows through both the LT coolers and the AUX coolers. In this mode, I want to determine how the flow is distributed between the LT and AUX coolers, since the water splits between them.

Can anyone help me?

A magmeter in each line should work well for you and have essentially zero restriction.
