Engineering
Heat Exchanger Effectiveness Calculator
Calculates heat exchanger effectiveness using the NTU-effectiveness (ε-NTU) method for counter-flow and parallel-flow configurations. Use it to evaluate or select heat exchangers when outlet temperatures are unknown.

Engineering
Thermal Stress & Expansion Calculator
Calculate how much a material expands or the thermal stress it develops when temperature changes, depending on whether it is free to move or constrained. Used in structural engineering, pipeline design, and materials selection.
