Heat Exchanger Sizing Calculator | Shell & Tube Design Tool

The heat exchanger sizing calculator estimates the heat duty, LMTD and correction factor F, required surface area and a preliminary shell-and-tube layout for sensible, condensing and boiling services. It adds Bell-Delaware shell-side checks, pressure drop, fouling, TEMA screening, cost optimisation and a datasheet export. How heat exchanger sizing works Sizing starts from an energy balance … Read more
