Question
A steam turbine receives hot & pressurized steam from the inlet (port 1 in the figure), produces work, and discharges steam at low pressure and temperature to the outlet (port 2). P1 = 1.5 x (1.8) MPa, T1 = 350 × (1.8) oC. P2 and T2 are given in the figure. The turbine is at a steady state. Kinetic energy and gravitational potential energy of the steam are negligible compared to its thermal energy. q is negligible Turbine w? T= m=16 kg/s 2+ P,=0.2 Mpa ! T;=150°C (a) Mass flow rate at the inlet is 10 kg/s. Compute the mass flow rate at the outlet. Show your reasoning (b) Determine the change of specific enthalpy of the steam between the inlet and the outlet. You can assume the specific heat of steam remains essentially constant during the process, with C, = 1.9 kl/kg.K (c) Compute the work produced by the steam turbine, per unit mass of steam. (d) Compute the power production from the turbine. Power is the work produced per time, and its most common unit is Watt (J/s).
