Parallel-flow epsilon-NTU heat exchanger

Calculates effectiveness and heat rate for a counterflow heat exchanger from UA and heat capacity rates.

Calculates heat exchanger effectiveness as actual heat rate divided by maximum possible heat rate.

Calculates number of transfer units from U, area, and minimum heat capacity rate.

Calculates the log-mean temperature difference for a parallel-flow heat exchanger.

Calculates fluid outlet temperature from inlet temperature, heat rate, mass flow, and specific heat.

Calculates required heat-transfer area from duty, U, and LMTD.
