a$)(5$ points$)$ Using the mean of your sections data for the water weights, calculate the percent error forthe graduated cylinder measures and the pipette measures. Use the equation below:

#$1.$ A nozzle takes atmospheric air at $300\frac{L}{m}in$ and $25C$ and heats it to $800C$ at the exit.

Assuming negligible velocity at the inlet and a constant pressure process, what is the exit velocity?

#$2.$ A steam turbine receives $1\mathrm{.}5k\frac{g}{s}$ of superheated steam at $2\mathrm{.}5$MPa,$700C$ and discharges at $20$kPa,$95\%$ quality. If heat lost from the surface of the turbine is $23$ kW $,$ what is the work output?

#$3.$ Refrigerant$-134$a is throttled from saturated liquid at $500$ kPa to $100$ kPa $.$ What is the temperature and the quality of the refrigerant after throttling?

#$4.$ In a feedwater heater, it is desired to have saturated vapor after $3k\frac{g}{s}$ of feedwater at $50C,500$kPa is mixed with superheated stean at $500C.$ What mass flow rate is required for superheated steam?

#$5.$ A transport tank for refrigerant $134$ a with volume of $5$ L is initially evacuated. It is to be filled from a line that carries saturated liquid refrigerant at $700$ kPa $.$ When the valve is opened, saturated liquid flows into the tank until the pressure reaches $500$ kPa $.$ At this pressure, the valve is closed. What is the temperature and quality of refrigerant in the tank when the valve is closed and how much mass has entered the tank?
