A supply line of steam at 0.8 MPa and quality of 0.95 (state 1) is mixing with steam at 0.8 MPa, 250 0C, and flowing at the rate of 1 kg/s (state 2) in a mixing chamber. After adiabatic mixing the flow rate is 2.3 kg/s (state 3), determine the phase of mixture at the exit when the pressure is 0.8 MPa. Draw schematic and P-v, T-v, and T-s diagrams to show the above processes accurately.

5. Determine the molal freezing point depression constant (Kf) (in °C⋅kg/mol) of water by using the data of three NaCl solutions . Use Equation 3 in the “Background and Procedure” file, the molality values of all solutes from Question s 1 – 3 and the freezing point depression ( ∆T) from Question 4. In your calculation, rewrite the symbol“m ” (the molality) as “mol/kg” so that the molal freezing point depression constant will have the correct unit. Make sure to...
