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
Convective Heat Transfer Calculator
Calculate convective heat transfer rate from a solid surface to a flowing fluid (or vice versa) using Newton's law of cooling. Use it to size heat exchangers, evaluate HVAC equipment, or estimate building heat loss.
