Q: Why does a cooling system using propylene glycol require pumps with oversized motors?
A: Because the viscosity and density of propylene glycol is higher than tap water.
Q: Why does a cooling system using propylene glycol require pumps with oversized motors?
A: Because the viscosity and density of propylene glycol is lower than tap water.
Q: Why does a cooling system using propylene glycol require pumps with oversized motors?
A: Because propylene glycol has a lower specific heat capacity and therefore requires a higher flow.
