### Text Transcription

An adiabatic open feedwater heater in an electric power plant mixes 0.2 kg/s of steam at 1000 kPa and 200°C with 5 kg/s of feedwater at 100 kPa and 60°C to produce feedwater at 1000 kPa at the outlet. Determine the outlet mass flow rate and the outlet pipe diameter when the outlet pipe diameter is 0.03 m.

### Diagram Explanation

The diagram is a simple representation of an adiabatic open feedwater heater. It features:

- **A cylindrical tank**: This is where the mixing occurs.
- **Inlet pipes**: There are two arrows pointing towards the tank indicating the inflow. One is labeled "steam" and the other "cool feedwater."
- **Outlet pipe**: An arrow pointing away from the top of the tank labeled "warm feedwater," indicating the mixed output.

Understanding this setup is vital for the calculations of mass flow rate and diameters in thermodynamic systems.
