Exchanged Heat in a Heat Exchanger
Exchanged Heat in a Heat Exchanger Formula
| \(\large{ Q = h \; A \; LMTD }\) |
Where:
| Units | English | Metric |
| \(\large{ Q }\) = exchanged heat duty | \(\large{ \frac{Btu}{lbm}}\) | \(\large{ \frac{J}{kg}}\) |
| \(\large{ A }\) = exchange area | \(\large{ft^2}\) | \(\large{m^2}\) |
| \(\large{ h }\) = heat transfer coefficient | \(\large{\frac{Btu}{hr-ft^2-F}}\) | \(\large{\frac{W}{m^2-K}}\) |
| \(\large{ LMTD }\) = logarithmic mean temperature differential | \(\large{ \frac{Btu}{lbm}}\) | \(\large{ \frac{J}{kg}}\) |
