    Finding thermodynamic properties for a Zn-Mg Alloy

    Hi! I am using a Zn-Mg alloy (52% and 48% respectively) as a phase change material in a thermal energy storage system, but I have been unable to track down important properties, such as specific heats and thermal conductivity. Is there any way to approximate these relatively accurately given...

    Thermodynamics: Pressure Drop over a Valve

    Hey Guys! Anyone able to help out here? I have already happily solved for T2 = 369.91K and m2 = 11.492kg However, for question 2.3, I'm terribly stuck. I'm not even sure what to make my control surface. How can I relate pressure outside the valve with the two thermodynamic states I have...
