Consider adiabatic flow of air through a duct. At a given point in the duct, velocity of air is 300 m/s, temperature is 330K and pressure is 180 kPa. Assume that the air behaves as a perfect gas with constant Cp = 1.005 kJ/kgK . The stagnation temperature at this point is ________ K (round off to two decimal places). 
    Correct answer is '374.77'. Can you explain this answer?

    Given:

    • Velocity of air, V = 300 m/s

    • Temperature of air, T = 330K

    • Pressure of air, P = 180 kPa

    • Specific heat at constant pressure, Cp = 1.005 kJ/kgK



    Concept:

    • Stagnation temperature is the temperature of the fluid when it is brought to rest isentropically (without any heat transfer) assuming no work is done on or by the fluid.

    • Stagnation temperature is given by the following formula:


    T0 = T + (V2 / 2Cp)


    Calculation:

    • Substituting the given values in the above formula, we get:


    T0 = 330 + ((3002) / (2 x 1.005))

    T0 = 374.77 K


    Answer:

    • The stagnation temperature at the given point in the duct is 374.77 K (rounded off to two decimal places).
