Extracted text: A steam turbine is designed to operate at a mass flow rate of 1.5 kg / h. Entry state to the turbine P1 = 2 MPa, T1 = 400°C and V1 = 60 m / s; the output state is P2 = 0.1 MPa, x2 = 0.97 and v2 = 150 m / s. The difference in height between the turbine inlet and outlet is 1 m. a) determine the power generated from the turbine. b) Calculate the power of the turbine, neglecting the kinetic and potential energy changes. Comment these two results. c) Calculate the turbine inlet and outlet cross-sectional areas, as well as the steam pipe diameters. d) if the environmental temperature is 27°C, What is the entropy production in the turbine? The heat loss from the turbine is given as 50 kw.
