In a combined heat-power plant with intermediate steam intake, steam enters the turbine at 7 MPa, 500°C at a flow rate of 28.7 kg/s and expands to a pressure of 0.4 MPa. At this pressure, 0.59 percent of the steam leaves the plant and the remaining steam expands to a pressure of 10 kPa. Some of the separated steam is used to heat the feedwater in an open feedwater heater. The remainder of the separated steam is used for heat treatments and exits the process heater as a saturated liquid at a pressure of 0.4 MPa. The exiting saturated liquid is then mixed with the feedwater from the feedwater heater and the mixture is pumped to the boiler pressure. Calculate the flow rate (kg/s) through the process heater using the enthalpy values given in the figure.
