The equation reads as Pfluid = ρgh, where ρ is the density of the liquid, g is the acceleration of gravity, and h is the height of the liquid (or depth of the fluid).
For example, if you had a fluid that with a density of (1. 08 x 103 kg/m3) and was 5. 00 m high, you would multiply (1. 08 x 103 kg/m3) x 9. 81 m/s2 (acceleration of gravity on Earth) x 5. 00 m. In this case, you would get the answer of 5. 30 x 104.
Since water is more dense than oil, you can expect water to exert more fluid pressure than oil at the same height.
The measurement shown on the scale is the total mass of the liquid and the cylinder.
For example, if your liquid had a mass of 125 g, you would divide that by 100 mL. Your resulting answer would be 1. 25 g/mL. However, make sure to pay close attention to the desired units of measurement. You may need to find the gallons per Liter (g/L) instead.
