1st:
Using the formula t =
determine the
Caa/29
coefficient of discharge.
“A" of tank
Note:
1. "A" depends on the size of your bottle,
2. "a" depends on the size of the hole you punched
3. Let the initial head of water equal to 10 cm
4. You can determine "t" through experiment
5. Hence, the only unknown is the value of Cd.
6. Repeat the process, try using head of water equal
to 15 cm, then 20 cm.
“a" of orifice
7. Hence, you have 3 values of Cd.
8. Tabulate and graph the results. Be creative.
Referred: 1.5 L water bottle or alike
You need to provide pictures for No.1 to No.3.
Show your solution in No.5. (x3 due to trial 1, 2,
and 3.
2nd:
Utilizing the same bottle, determine the average
velocity of the fluid flowing through the water using
the formula Q = CqA¿V¢ -
"A" of tank
Note:
• Let Q = Volume / time. Use a beaker or measuring
cup to determine the volume, then record the time
“a" of orifice
until water "runs" out. Be careful, volume refers
only to the amount of water above the orifice;
water below the orifice won't flow out.
Trials 1, 2, 3 = 100 ml, 500 ml, 1000 ml
Let Cd = average Cd obtained from the previous
experiment.
• At = area of orifice.
• Hence, only unknown is Vt; but in this case we'll
call it average velocity because the formula Q =
CaAtVt applies only if the liquid head is constant.
Compare your obtained V-ave with V-theoretical
(sq. rt. of 2gh). Share your thoughts and explain.
• Show pictures and calculations.
Include the procedure/steps using your own words.
