A steam power plant is located in the northern part of the country. Steam in the plant flows steadily through a 0.104-m diameter pipeline from the steam generating unit (SGU) to the steam turbine. At the SGU end, the steam conditions are determined to be P = 4 MPa, t = 400°C, h = %3D 3,224.1 kJ/kg, and specific volume = 0.175 %3D m°/kg. At the steam turbine end, the conditions are found to be P = 3.5 MPa, t = 392°C, h = 3,181 kJ kg, and specific volume %3D = 0.214 m°/kg. Heat loss from the pipeline %3D is 5.45 kJ/kg. Determine the steam mass flow rate in kg/s.

Question
A steam power plant is located in the
northern part of the country. Steam in the
plant flows steadily through a 0.104-m
diameter pipeline from the steam
generating unit (SGU) to the steam turbine.
At the SGU end, the steam conditions are
determined to be P = 4 MPa, t = 400°C, h =
%3D
%3D
3,224.1 kJ/kg, and specific volume = 0.175

m/kg. At the steam turbine end, the
conditions are found to be P = 3.5 MPa, t =
392°C, h = 3,181 kJ kg, and specific volume
= 0.214 m /kg. Heat loss from the pipeline
is 5.45 kJ/kg. Determine the steam mass
flow rate in kg/s.
