Chapter 15, Problem 70

(choose chapter or problem)

Suppose a power plant delivers energy at 880 MW using steam turbines. The steam goes into the turbines superheated at 625 K and deposits its unused heat in river water at 285 K. Assume that the turbine operates as an ideal Carnot engine.

\((a)\) If the river flow rate is \(\mathrm {37~ m^3/s}\), estimate the average temperature increase of the river water immediately downstream from the power plant.

\((b)\) What is the entropy increase per kilogram of the downstream river water in \(\mathrm {J/kg \cdot K}\)?
