  • Q 220233

    Question 220233:


    Ts the static temperature (SAT)
    Tt the total temperature (TAT)
    Kr the recovery coefficient
    M the Mach number

    The total temperature can be expressed approximately by the formula:

    BGS answer: Tt=Ts(1+0.2M2)
    but isn't this:
    Tt=Ts(1+0.2KrM2)
    ?

    Hi,

    The question is asking what gives an 'approximate' answer. By leaving out the recovery coefficient (Kr) it means the answer is only approximate.

    Please remember we don't write the music, we only play the piano.
