The hydrometer of Problem 2.87 is weighted so that in fresh water the stem is just submerged.
(a) What is the maximum specific gravity that can be read?
(b) What mass of mercury is required?
Problem 2.87
The hydrometer shown in Fig. P2.87 with no mercury has a mass of 0.01 kg. It is designed to float at the midpoint of the 12-cm-long stem in pure water.
(a) Calculate the mass of mercury needed.
(b) What is the specific gravity of the liquid if the hydrometer is just submerged?
(c) What is the specific gravity of the liquid if the stem of the hydrometer is completely exposed?
