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.

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.
