Heat Load and Water Flow

The Heating and Cooling Capacity for Water Flow calculator computes the ton of heat capacity associated with a volumetric flow of water (q) and a change in temperature (?t).

INSTRUCTIONS: Choose units and enter the following:

• (q) Flow Rate of Water
• (ΔT) Change of Temperature.
• (c_p) Specific Heat of Water
• (ρ) Mean Density of water

Heat Load (h): The calculator return the cooling/heating in BTUs per Hour.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

Heat loads of fluids in BTUs/hour are computed as follows:

h = c_p • ρ • q • ΔT

where;

• c_p is the specific heat ( J /(kg K) )
• ρ is the mean density
• q is the flow rate
• ΔT is the change in temperature.
