Heat Exchanger Sizing Calculator (LMTD And NTU)
Heat Exchanger Sizing Calculator (LMTD And NTU): a planned Super Calculator tool. Stub page: the tool, its formula and a worked example are not published yet.
Heat Exchanger Sizing Calculator (LMTD And NTU) is a planned calculator in the engineering section of Super Calculator, covering building services engineering.
What this calculator will compute
Inputs: hot and cold inlet temperatures and flow rates, fluid properties, target duty or outlet temperature, flow arrangement, overall heat transfer coefficient and fouling factors.
Outputs: heat duty, LMTD and correction factor, required area, outlet temperatures, effectiveness and NTU, pinch point and surface margin for fouling.
Formula, recorded as scope and not yet verified against a primary source: Q = U A F delta T_lm, where the log mean temperature difference is (delta T1 - delta T2)/ln(delta T1/delta T2) and F corrects for multi-pass and cross flow arrangements. The effectiveness-NTU method applies where outlet temperatures are unknown.
