Steam flows steadily into a turbine with a mass flow rate
Chapter 5, Problem 56P(choose chapter or problem)
Steam flows steadily into a turbine with a mass flow rate of \(26 \mathrm{~kg} / \mathrm{s}\) and a negligible velocity at \(6 \mathrm{MPa}\) and \(600^{\circ} \mathrm{C}\). The steam leaves the turbine at \90.5 \mathrm{MPa}\) and \(200^{\circ} \mathrm{C}\) with a velocity of \(180 \mathrm{~m} / \mathrm{s}\). The rate of work done by the steam in the turbine is measured to be \(20 \mathrm{MW}\). If the elevation change between the turbine inlet and exit is negligible, determine the rate of heat transfer associated with this process.

ANSWER:
Problem 56P
Steam flows steadily into a turbine with a mass flow rate of 26 kg/s and a negligible velocity at 6 MPa and 600°C. The steam leaves the turbine at 0.5 MPa and 200°C with a velocity of 180 m/s. The rate of work done by the steam in the turbine is measured to be 20 MW. If the elevation change between the turbine inlet and exit is negligible, determine the rate of heat transfer associated with this process.
