8: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
The viscosity and density of propylene glycol is higher than tap water.
8: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
The viscosity and density of propylene glycol is lower than tap water.

8: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
Propylene glycol has a lower specific heat capacity and therefor requires a higher flow.
