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
Pipe Flow & Pressure Drop Calculator
Calculates pressure drop along a pipe using the Hazen-Williams equation, accounting for pipe material, flow rate, diameter, length, and elevation change. Use it to size water distribution pipes, fire suppression systems, and irrigation lines.
