OBJECTIVE or GOAL
Determine the volume of an empty column.
- Use Volume = pi x radius2 x Length
- pi = 3.14
- r2 and Length should be converted to centimeters
- Diameter of column divided by 2 = radius
- radius x radius = r2
- 3.14 x r2 x L = Volume in cm3
- cm3 = 1 mL
The empty column volume of 4.6 mm x 150 mm is 2.5 mL.
pi = 3.14
4.6 mm becomes 0.46 cm and 150 mm becomes 15 cm.
0.46 cm divided by 2 = 0.23 cm radius
0.23 cm x 0.23 cm = 0.0529 cm2
3.14 x 0.0529 cm2 x 15.0 cm = 2.49cm3
