E-CodeVenturi meter and Pitot tube — a TI-84 Plus CE program
VENTURI is a TI-BASIC program for the TI-84 Plus CE. Venturi: flow rate from the differential pressure with a discharge coefficient, velocities, and the pressure lost. Pitot: velocity from a manometer reading.
What it asks for and what it shows
It asks for 5 values at its prompts, after you pick option 1 from its menu. In the example below it shows Q L/S, V1 M/S, V2 M/S, BETA, LOSS KP.
Example run
One of its oracle test cases: “water venturi”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Menu | option 1 |
| Input 1 | 100 |
| Input 2 | 50 |
| Input 3 | 0.98 |
| Input 4 | 30 |
| Input 5 | 998 |
| The screen shows | |
Q L/S= | 15.40922094 |
V1 M/S= | 1.961962945 |
V2 M/S= | 7.84785178 |
BETA= | 0.5 |
LOSS KP= | 1.188 |
How it's checked
5 test cases, each checked against an independent method. Replayed key by key on a virtual TI-84 Plus CE, they make 25 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 “Venturi meter and Pitot tube” (VENTURI).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
