EXPERIMENT 9
BERNOULLI’S EQUATION
OBJECTIVE
To analyze the effect of varying a pipe’s height and radius on the fluid’s pressure and speed.
PROCEDURE
1. Access the simulation package thru https://ophysics.com/fl2.html.
2. Study the controls of the simulation package.
3. Set the initial speed value to 3 m/s and use the value for initial pressure assigned to your group as below.
GROUP NUMBER INITIAL PRESSURE (P1)
1 500,000 Pa
2 600,000 Pa
3 700,000 Pa
4 800,000 Pa
5 900,000 Pa
6 1,000,000 Pa
4. At constant initial and final raddi of 1 m, set the initial and final height to the values reflected in table 1.
Click RUN to start the simulation and record final pressure and speed values. These are the simulated values.
5. Use the continuity and Bernoulli’s equations to solve for the final speed and pressure, respectively. Record
these as the computed values in table 1.
6. Set the constant initial and final height to 3 m and 5 m, respectively and use the raddi values in table 2. Click
RUN to start the simulation and record final pressure and speed values.
7. Use the continuity and Bernoulli’s equations to solve for the final speed and pressure, respectively. Record
these as the computed values in table 2.
8. Calculate the percentage difference values between simulated and computed values. Record these on
tables 3 and 4.
