Title: What is the temperature difference across a window if the conductive heat flow rate across it is 20 ... Post by: hockeyguy9 on Jan 21, 2018 What is the temperature difference across a window if the conductive heat flow rate across it is 20 J/s? The window is 4.5 m2 in area that has an R-value of 2.5 m2 C/W.
What will be an ideal response? Title: What is the temperature difference across a window if the conductive heat flow rate across it is 20 ... Post by: Tmheath on Jan 21, 2018 We find the rate of heat transfer from
rate of heat transfer = A DT/R = 4.5 m2 x DT/(2.5 m2 C/W). This allows us to find DT. We have DT = R x (rate of heat transfer)/A = (2.5 m2 C/W) x (20 J/s)/(4.5 m2) = 11.1 C. |
