1 kg of steam at initial conditions of 5.1 MPa and 370 °C expands in a turbine until it becomes saturated. It is withdrawn and reheated to 340°C. After further expansion in the turbine to 160 , part of the steam is extracted for feedwater heating. The remaining steam expands to the condenser pressure of 0.018 MPa. find Wnet, Ec, Ee and the ideal steam rate. Remember, 1. For values taken from the steam tables: Use them as is, do not round off. 2. For values obtained by interpolation and final answers obtained by solving, use FOUR (4) decimal places. 3.

You, a process design engineer, are tasked to build a powerplant with a net output of 1 MW. First, in an industrial boiler, coal is burned to heat and pressurize 1.6 kg/s of water pumped from an underground reservoir (25 oC, 1 atm) to High Pressure Steam (44 atm, 450 oC). The industrial boiler is insulated, but due to the high temperatures and the nature of the process there are inevitably heat losses. As such, the total heat losses of the whole system is around 20% of the heat from the coal. The High-Pressure Steam, moving at a linear velocity of 70 m/s, is then used to drive a turbine. The low pressure steam from the turbine is used to preheat the boiling water and then released to the atmosphere as saturated steam (100oC and1atm) at a velocity of 10 m/s via an exhaust 10 m above the turbine inlet. How much heat is needed for the powerplant? Use the following values of enthalpy: Water from reservoir 25oC; 1atm H=104.93 kJ/kg High Pressure Steam 450oC; 44atm H=3324.63 kJ/kg Low…
250 degrees saturated steam enters a steam coil. The steam is condensed in the coil, leaving as a saturated liquid also at 250 degrees. The rate of heat loss to the environment is 1.5 J/s. The methanol to be heated is fed into the fermenter at 20 degrees and is at 45 degrees. If 150kg of biomass with a specific enthalpy change of 81.5 J/g flows into the process per hour, how many kilograms of steam are needed per hour? What is the volumetric flow of steam?
