Hello Mathcad community,
Can anyone tell me where the error is?

Solved! Go to Solution.
There is a unit mismatch in function H
Guess it should rather read
In the plot at the end you should not use the desired units in parentheses.
If the plot should be shown in standard units (which are seconds and meter in your case anyway) its not necessary to do anything:
To show the units you may either use the labels or divide by the desired units:
That kind of division is necessary in case you don't want the plot shown in default units.
Here is the same plot using minutes at the x-axis and feet at the y-axis:
The difference lies of course just in the scaling of the axis.

Thank you Werner.
There were two errors in the development. One regarding the units and the other was the roughness value.

Both our fixes for the unit mismatched are equivalent.
Sure I did not catch the missing "0." in the definition of "e"
BTW, is "draining_time" supposed to be the position where h1=0? That's not the case.
