Water cooling is often used in order to help dissipate or at least transfer large amounts of dissipated power (heat) which can be typical of many power electronics and repetitive pulsed power applications. The formulas on this page allow one to calculate the temperature rise for a given water cooling application where the power dissipation and flow rate are known. By knowing the density of water, one can determine the mass flow rate based on the volumetric flow rate and then solve for the temperature rise.
DT is the temperature rise or Delta (Deg C)
q is the heat load or dissipated power (W or J/sec)
mdot is the mass flow rate (gm/sec)
Cp is the specific heat of water (4.186 J/gm deg C)
