1. A manometer tube is filled with two type of liquids. The density of liquid 1 is ρ1 = 0.8 g.cm-3, and the density of liquid 2 is ρ2 = 1 g.cm-3, and height h1 = 10 cm, then what is the height of h2.
Density of liquid 1 = 0.8 g.cm-3
Density of liquid 2 = 1 g.cm-3
Height 1 = 10 cm
Wanted: Height 2
2. The height of the water is 50 cm, and the height of another liquid is 30 cm. What is the density of another liquid?
Acceleration due to gravity (g) = 10 m/s2
The height of water (h1) = 50 cm
Density of water (ρ1) = 1.00 x 103 kg/m3 = 1000 kg/m3
Height of another liquid (h2) = 30 cm
Wanted : The density of another liquid.
pa + ρ1 g h1 = pa + ρ2 g h2
