    The first law of thermodynamics for open systems

    Hi Chester, V(dot above the letter) Volume flow rate. Q(dot) Heat release rate. P is the pressure at 1atm Thanks for your help.

    The first law of thermodynamics for open systems

    Ahhh That would make sense. Thanks! So do I just use the mas flow rate and the other known values in the equation T2= T1 + Qdot/ P.(Vdot).Cp?

    Is it m=pVA = 1.19 kg/s

    The first law of thermodynamics for open systems

    Thanks very much. Mdot for propane = 1.25 x 10 -3. I don't know the mass flow rate for the air. Sorry!

    Hi Chestermiller, Are you able to expand this a little as I am still confused. Any help is much appreciated!
