Chapter 3, Problem 99P
The density of a liquid is to be determined by an old 1-cm-diameier cylindrical hydrometer whose division marks are completely wiped out. The hydrometer is first dropped in water, and the water level is marked. The hydrometer is then dropped into the other liquid, and it is observed that the mark for water has risen 0.3 cm above the liquid-air interface (Fig. P3-99). If the height of the original water mark is 12.3 cm. determine the density of the liquid.

Here, a liquid's density is to be determined by a 1-cm diameter cylindrical hydrometer whose division marks are non visable. The hydrometer is first dropped in water, and the water level is marked. The hydrometer is then dropped into the 'liquid x', and it is observed that the mark for water has risen 0.85 cm above the liquid–air interface. In this case, the height of the originalwater mark is 12.7 cm. As such, how would I determine the density of the liquid?

For a liquid with the contact angle of 53.6 degrees and surface tension of 0.075 N/m, capillary rise
is 2.50 m. What is the expected capillary rise in meters if the liquid is replaced with another with
a contact angle of 12.7 degrees and a similar surface tension? (answer should be accurate to 2
decimal places)
