In a steam power station, steam flows stedily through a 0.2 m diameter pipeline from the boiler to the turbine. At the boiler end, the steam conditions are found to be: p=4 MPa, t=400°C, h=3213.6 kJ/kg, and v=0.073 m³/kg. At the turbine end, the conditions are found to be:p=3.5 MPa,1=392°C, h=3202.6 kJ/kg, and v = 0.084 m³/kg. There is a heat loss of 8.5 kJ/kg from the pipeline. Calculate the steam flow rate.
