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 = 60m/ 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. The heat loss from the turbine is given as 5 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.

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
