Hot oil heat exchanger calculator
WebThe basic design calculation for any heat exchanger is the determination of heat transfer area. Most generally, this is done using. although in practice it is more common to assume that fluid properties can be treated as constant at the bulk average values, and approximate the design equation with: To use this equation, it is necessary to ... Web3. What you need to apply is the engineering equations for a heat exchanger. In the below equation, Q ˙ is the heat transfer rate, U A is the heat transfer coefficient times the area and Δ T m is the log mean temperature difference (LMTD). Q ˙ = U A Δ T m. For this problem there are 3 barriers to the heat transfer in series.
