Determine the height of purple liquid in a U tube. Density of purple liquid is 0.7 g/cc , density of blue liquid = 1.4 g/cc , density of mercury = 13.6 g/cc.

Expert Answer:

Considering equilibrium state, the pressure of liquids at the same level must be equal.

Pressure due to h cm of purple liquid + pressure due to (15-h) cm of mercury = 

pressure of 15 cm of blue liquid.
