Textbook Question
Chapter 15, Problem 70GP
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 37 m3/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 J/kg • K?
