E-CodeHydraulic jump — a TI-84 Plus CE program
HYDJUMP is a TI-BASIC program for the TI-84 Plus CE. Rectangular channel: Froude number, sequent depth, downstream velocity and Froude number, head loss, power dissipated and approximate jump length.
What it asks for and what it shows
It asks for 2 values at its prompts. In the example below it shows FR1, Y2 M, V2 M/S, FR2, LOSS M, P KW/M, LEN M.
Example run
One of its oracle test cases: “strong jump”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Input 1 | 0.4 |
| Input 2 | 6 |
| The screen shows | |
FR1= | 3.028912664 |
Y2 M= | 1.525044874 |
V2 M/S= | 1.573724184 |
FR2= | 0.4068673158 |
LOSS M= | 0.5835887751 |
P KW/M= | 13.74001412 |
LEN M= | 9.150269243 |
How it's checked
4 test cases, each checked against an independent method. Replayed key by key on a virtual TI-84 Plus CE, they make 30 checks.
How E-Code checks every program
Run it or put it on your calculator
- Open the library in the TI-84 Plus CE calculator and pick “Hydraulic jump” (HYDJUMP).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
