Thermodynamics Tee Junction Problem

  • #1

Homework Statement


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).


Homework Equations


N/A

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.
