Water at p1 = 20 bar, T1 = 400°C enters a turbine operating at steady state and exits at p2 = 1.5 bar, T2 = 260°C. The water mass flow rate is 4000 kg/hour. Stray heat transfer and kinetic and potential energy effects are negligible.
(a) Determine the power produced by the turbine, in kW;
(b) The rate of entropy production in the turbine, in kW/K.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
