Steam enters a turbine operating at steady state at 2 MPa,
Chapter 4, Problem 4.48(choose chapter or problem)
Steam enters a turbine operating at steady state at 2 MPa, \(360^{\circ} \mathrm{C}\) with a velocity of 100 m/s. Saturated vapor exits at 0.1 MPa and a velocity of 50 m/s. The elevation of the inlet is 3 m higher than at the exit. The mass flow rate of the steam is 15 kg/s, and the power developed is 7 MW. Let \(g=9.81 \mathrm{~m} / \mathrm{s}^{2}\). Determine (a) the area at the inlet, in \(\mathrm{m}^{2}\), and (b) the rate of heat transfer between the turbine and its surroundings, in kW.
