[填空题]
Suppose a power plant delivers ener -txu;1c1 hfi.tx-fzqgy at 980 MW using s drc8* 2p mwd5n7jgmmf dq8:6qteam turbines. The steam goes into the turbines superheated at 625m 6q8:nmc*d5 2gd w jrfqpd87m 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 $37m^3/s$ estimate the average temperature increase of the river water immediately downstream from the power plant. $C^{\circ} $
(b) What is the entropy increase per kilogram of the downstream river water in $J/kg \cdot\,K?$ $J/kg\cdot\,K$
