To see the original equations, EQ1 and EQ2, in terms of the primitive
variables listed above, we can use function EVAL applied to each of the
equations, i.e.,
µ @@@EQ1@@ µ @@@EQ2@@
. The equations are listed in the stack
as follows (small font option selected):
We can see that these equations are indeed given in terms of the primitive
variables b, m, y, g, S
o
, n, Cu, Q, and H
o
.
In order to solve for y and Q we need to give values to the other variables.
Suppose we use H
0
= 5 ft, b = 1.5 ft, m = 1, n = 0.012, S
0
= 0.00001, g =
32.2, and Cu = 1.486. Before being able to use MSLV for the solution, we
need to enter these values into the corresponding variable names. This can
be accomplished as follows:
