We can type in the equation for E as shown above and use auxiliary

variables for A and V, so that the resulting input form will have fields for the

fundamental variables y, Q, g, m, and b, as follows:

• First, create a sub-directory called SPEN (SPecific ENergy) and work

within that sub-directory.

• Next, define the following variables:

• Launch the numerical solver for solving equations: ‚Ï@@OK@@.

Notice that the input form contains entries for the variables y, Q, b, m,

• Try the following input data: E = 10 ft, Q = 10 cfs (cubic feet per

second), b = 2.5 ft, m = 1.0, g = 32.2 ft/s

• Solve for y.
