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.
