Steam steadily enters an adiabatic turbine at 16 MPa and 480°C (State 1) with a mass flow rate of 600 kg/s. At an intermediate stage, 120 kg/s of the steam is bled off at 1 MPa and 280°C (State 2). The remaining steam exits the turbine as saturated vapor at 8 kPa (State 3). (a) Calculate the power produced by the turbine, in MW. Consider the entire steam flow of 600 kg/s expands from 16 MPa and 480°C (State 1) directly to saturated vapor at 8 kPa (State 3) with no bleed-off steam. (b) Determine the power produced by the turbine, in MW. (c) Is the power calculated in (a) higher or lower compared to that calculated in (b)? Explain.

Step 1
(a) To calculate the power produced by the turbine when there is no bleed-off steam, we can use the steady flow energy equation: Power = (mass flow rate) * (specific enthalpy change) Show more…

Steam at $6 \mathrm{MPa}$ and $500^{\circ} \mathrm{C}$ enters a two-stage adiabatic turbine at a rate of $15 \mathrm{~kg} / \mathrm{s}$. Ten percent of the steam is extracted at the end of the first stage at a pressure of $1.2 \mathrm{MPa}$ for other use. The remainder of the steam is further expanded in the second stage and leaves the turbine at $20 \mathrm{kPa}$. Determine the power output of the turbine, assuming $(a)$ the process is reversible and $(b)$ the turbine has an isentropic efficiency of 88 percent. Answers: (a) $16,290 \mathrm{~kW},$ (b) $14,335 \mathrm{~kW}$

A well-insulated turbine operating at steady state is sketched in Fig. P4.29. Steam enters at $3 \mathrm{MPa}, 400^{\circ} \mathrm{C}$, with a volumetric flow rate of $85 \mathrm{~m}^{3} / \mathrm{min}$. Some steam is extracted from the turbine at a pressure of $0.5 \mathrm{MPa}$ and a temperature of $180^{\circ} \mathrm{C}$. The rest expands to a pressure of $6 \mathrm{kPa}$ and a quality of $90 \%$. The total power developed by the turbine is $11,400 \mathrm{~kW}$. Kinetic and potential energy effects can be neglected. Determine (a) the mass flow rate of the steam at each of the two exits, in $\mathrm{kg} / \mathrm{h}$. (b) the diameter, in $\mathrm{m}$, of the duct through which steam is extracted, if the velocity there is $20 \mathrm{~m} / \mathrm{s}$.
