The basic heat exchanger design equation can be used for a variety of types of heat exchangers like double pipe heat exchangers or shell and tube heat exchangers.
Water cooled heat exchanger calculation.
About equivalent to the heat generated by striking 1 stick match.
Enter the btu requirement temp in temp out and gpm are shaded for hot and cold enter two of the three shaded portions for hot enter two of the three shaded portions for cold.
The specific heat of the oil is 2 2 kj kg k.
Consider a parallel flow heat exchanger which is used to cool oil from 70 c to 40 c using water available at 30 c the outlet temperature of the water is 36 c.
The rate of flow of oil is 1 kg s.
The currently calculating value will always be highlighted in green.
Btu calculator btu formulas for water circulating heat transfer.
When btu requirement is known most applications.
Calculate the required heat transfer area based on values needed.
Assume the cpu inserts a constant rate of energy q into the cooling system.
Enter the fluid data and enter 5 of the 6 available inputs under flow rates and temperatures.
Overall heat transfer coefficient calculate overall heat transfer coefficients for walls or heat exchangers.
A box will be highlighted yellow if it needs input.
The formulas on this page allow one to calculate the temperature rise for a given water cooling application where the power dissipation and.
These templates use s i.
Cooling of liquid light hydrocarbons.
In other words the rate of heat transfer is directly proportional to mass flow rate.
Since you cannot mess with mother nature it is very naive to think it works any other way.
Heat transfer theory tells us that the log mean temperature difference is the average temperature difference to use in heat exchanger design equation calculations.
They will also calculate the number of tubes needed for a shell and tube heat exchanger and to calculate the pipe length needed for a double pipe heat exchanger.
A btu is a relatively small amount of energy.
This calculator will help determine which exchanger has enough heat transfer capacity for your system.
Download the excel spreadsheet templates in this article to make preliminary heat exchanger design calculations.
This video describes how much steam is required to raise temperature of water to a certain degree in a heat exchanger.
A btu is an abbreviation for b ritish t hermal u nit which is the amount of energy required to raise 1 pound of water 1 degree fahrenheit at sea level.
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.
Cooling of air or flue gas.
