Assumptions made
1. Equation not solvable by using 1.4/M-1.4*M-0.2*M^3
Equation solved using -1.4*M-1.4*M^3+0.7*M^2
approximate curve.
2. Assumptions made
M2=1;
P3=17.4psi
P2=10 psi
A(x)=Ac(x)
A2= 10*2.5 in^2
A3= (10+0.0349*x)*2.5 in^2
T2=1715 R
Tt2=2185 R
ER =0.5
n=2 i.e PA^2=constant
pw/ptf = p/pt
M3=1.95
3. Curve fit temperature curve in R and in
u(i)= -0.419108 *y(i)^3+13.5919 *y(i)^2+119.154 *y(i)+3962.68;Will differentiating this give dTt/dx or should it be derived from the formula given as
4. Should distances be taken from 0 in or from -10 in as given in Billigs Experiment?
5. How to use the values given by him? And what they represent?
6. Which formulae to be used i.e is it enough to stick with these generalized equations or use other specifics?
8. Is it valid to use Tt(x) curve fit data from Billigs Exxperiment as his conditions are quite different from ours?
9. Is it necessary to calculate U(x) too?
10. How to intepret this data and the graph following it?
11. Is using this data valid?
