    Adiabatic filling of a tank - Minimum work required

    Nope, ideal gas law cannot be applied. Data for Cp are available as polynomial as function of temperature, so i cannot give you an exact value right now. The energy balance for the system is: d(U)/d(t)= (Mass flow in*)Enthalpy In - (Mass flow out)*Enthalpy out + Heat exchanged + Work where U...

    Adiabatic filling of a tank - Minimum work required

    Thanks for your welcome! Sorry, thought the procedure (energy balance or kind of) was almost independent from the kind of substance involved. :) Substance is Ethane. I've to do the same, also, with Acetylene, but on different pressures and temperatures conditions. (the one I've wrote above are...

    Adiabatic filling of a tank - Minimum work required

    Hi guys, need an help about that problem That's an adiabatic filling of a reservoir (tank) from a line. Line is at 350 K and 8 MPa. The tank is, in the final state, at 365 K and 6 MPa. Tank is insulated (no heat exchanged during the process), and only one stream enter in the tank. How can i...
