Solving equations 1 and 2 for K gives:
K = P
D
× (T
A
+ 273 × C) + Q
JMA
× P
D
2
(3)
where K is a constant pertaining to the particular part. K can be determined from equation
(3) by measuring P
D
(at equilibrium) for a known T
A
. Using this value of K, the values
of P
D
and T
J
can be obtained by solving equations (1) and (2) iteratively for any value of
T
A
.
