Heat Loss from R-Value Formula
The following formula is used to calculate the Heat Loss from R-Value.
HLR = SA * dT / R
Variables:
- HLR is the Heat Loss from R-Value (BTU/hr)
- SA is the surface area (ft^2)
- dT is the temperature differential (F)
- R is the R-value
To calculate the heat loss, multiply the surface area by the temperature differential, then divide by the R-value.
How to Calculate Heat Loss from R-Value?
The following steps outline how to calculate the Heat Loss from R-Value.
- First, determine the surface area (ft^2).
- Next, determine the temperature differential (F).
- Next, determine the R-value.
- Next, gather the formula from above = HLR = SA * dT / R.
- Finally, calculate the Heat Loss from R-Value.
- 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.
surface area (ft^2) = 5
temperature differential (F) = 7
R-value = 8HLR = SA * dT / R = ?
