Heat Flow Formula
The following formula is used to calculate the Heat Flow.
HF = dT / R * HTC
Variables:
- HF is the Heat Flow ( )
- dT is the temperature difference
- R is the R-value
- HTC is the overall heat transfer coefficient
To calculate heat flow, divide the temperature difference by the R-value, then multiply by the heat transfer coefficient.
How to Calculate Heat Flow?
The following steps outline how to calculate the Heat Flow.
- First, determine the temperature difference.
- Next, determine the R-value.
- Next, determine the overall heat transfer coefficient.
- Next, gather the formula from above = HF = dT / R * HTC.
- Finally, calculate the Heat Flow.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
temperature difference = 4
R-value = 5
overall heat transfer coefficient = 10HF = dT / R * HTC = ?
