Problem $2-1-15$

Steam enters a turbine through a duct with a diameter of $0\mathrm{.}75$ m at $10$MPa,$600,$ and $100\frac{m}{s}.$ It exits the turbine through a duct with a diameter of $1$ m at $400$ kPa and $200.$

Part A

For steady state operation, determine the exit velocity.

Express the exit velocity in meters per second to three significant figures.
