Homework Help: Thermodynamics Tee Junction Problem

  1. Mar 5, 2016 #1
    1. The problem statement, all variables and given/known data
    T junction

    5 kg/s of methane enters on one side at P1 = 1 MPa, T1 = 400 K,

    and 1kg/s of methane enters on the otheras a saturated liquid at P2 = 1 MPa.

    The two streams are mixed and emerge at P3 = 1 MPa.

    Determine the temperature of the discharge stream (T3).

    2. Relevant equations

    3. The attempt at a solution
    I know I need an energy balance and mass balance. So what I have tried to do is write E°in=E°out as the sum of the mass flow times enthalpy for both inlet pipes, but I get stuck after that. Please walk me through the process.
