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.

Chemical Engineering
Heat Exchanger Effectiveness Calculator
Computes heat exchanger thermal effectiveness (ε) using the NTU-effectiveness method for parallel-flow, counter-flow, and cross-flow configurations. Used by engineers to evaluate or size heat exchangers without knowing outlet temperatures.
