Homework Statement
air flows through a device such that the stagnation pressure is 0.6 MPa, the stagnation temperature is 400° C, and the velocy is 570 m/s.
Determine the static pressure and temperature of the air at this state.
Homework Equations
Tt=T + V2 / 2 Cp where Cp is 1.005 Kj/ Kg* ° K
The Attempt at a Solution
what I did was Isolate for T since that is what I am looking for. [/B]
2 Cp x Tt - v2 = T
somewhere in here I know I have to throw in 1000m2/s2/ Kj/kg °k
when I do that I get -323.5 ° K
the answer is 518.6 ° K
Someone please let me know where I have gone wrong. Thank you
