Steam enters a turbine at 10 MPa, 410^oC, and 80 m/s, and leaves at 10 kPa, 90 percent quality and 50 m/s. Steam flows steadily through the turbine at 10 kg/s and the heat loss from the turbine is 0.5 kW. Neglecting potential energy changes, determine

1. The power output of the turbine (kW)
2. The turbine inlet area (m²)
3. The turbine outlet area (m²)
4. The volume flow rate of steam at turbine outlet (m³/s)

Steam expands in a thermally isolated turbine steadily.

The inlet pressure is 1MPa and temperature is 800 C, and the exit state is 300 kPA and 150 C.

a- Determine the power generated by the turbine per unit mass flow rate of steam.

b- Evaluate the entropy generation rate per unit mass flow rate of steam and drive a conclusion whether the turbine operates reversibly, irreversibly or the operation is impossible.

a proposal has been made to install an industrial robot to replace the welder. The cell would consist of the robot, two welding fixtures, and the fitter who loads and unloads the parts. With two fixtures, the fitter and robot would work simultaneously, the robot welding at one fixture while the fitter unloads and loads at the other. At the end of each work cycle, they switch places. The robot would use gas metal arc welding instead of shielded-metal or flux-cored arc welding, but the welding speed would remain the same 300 mm/min. The electrode wire spool must be changed every 10 work parts, which takes 5.0 minutes and is accomplished by the fitter. Determine (a) arc-on time and (b) production rate for this work cell.
