Question the whole class doesn't understand
Ok, so were getting along ok with questions i guess, but were all fumbled on this qustion, not sure if were using the right formulae or not, were just trying to figure it all out.
Q. Given MN 0.70, measured impact temp = - 48° C, the recovery factor
of
the temperature probe (Kr) is 0.85, the OAT is:
a) - 60° C
b) - 45° C
c) - 65° C
d) -51° C
Answer: c) -65° C
So we now know that the equation is Ts = Tt/(1 + 0.2KrM²)
Ts IS the OAT, so it’s a question of working the rest of it out, I cant
get
anywhere near to -65° C.
