Homework Help: Basic thermo question

  1. Sep 23, 2006 #1
    I have question (probably figured that). I have an open system with mass flow rate going into one inlet and going through two outlets. I have all the terms for the two outlets (mass flow, velocity, area, temp, pressure). However for the inlet I'm missing the Velocity and Area.

    In solving for the Velocity I figured I could you use the following equation

    0 = h1 – h2 + (V1^2– V2^2)/2

    But being I have two outlets in this case can I just plug in a 3rd term?

    0 = h1 – h2 – h3 + (V1^2– V2^2 – V3^2)/3
