Homework Help: Rayleigh Flow and Stagnation Conditions

  1. Mar 18, 2015 #1
    1. The problem statement, all variables and given/known data\

    The question I want to ask is how do you relate conditions such as To* and To,1 and To,2, where To,1 and To,2 are the stagnation conditions at the entrance and exit.

    This is the problem I was doing.

    Standard atmospheric air is drawn steadily through an isentropic converging nozzle into a frictionless diabatic (q = 500 kJ/kg) constant aread duct. For max flow, determine the values of static temperature, static pressure, stagnation temperature, stagnation pressure, and flow velocity at the inlet [section(1)] and exit [section(2)] of the constant area duct.

    2. Relevant equations

    3. The attempt at a solution
    I know that for maximum flow, To,2 = To*, but I'm not sure if it's due to the fact it's coming in supersonically and because of the heating involved or am I completely off. I also ran into a problem where To,1 = To*
