Textbook Question
Chapter 3, Problem 84P
The stem of a glass hydrometer used to measure specific gravity is 5 mm in diameter. The distance between marks on the stem is 2 mm per 0.1 increment of specific gravity. Calculate the magnitude and direction of the error introduced by surface tension if the hydrometer floats in kerosene. (Assume the contact angle between kerosene and glass is 0°.)

PROBLEM
●
A hydrometer is used to measure the
specific gravity of liquids. For a certain
liquid a hydrometer reading indicates a
specific gravity of 1.15. What is the liquid's
density and specific weight? Express your
answer in Sl units.
a drum has gasoline s.g=0.9, with oil s.g=0.8 and sea water s.g=1.03. the depth of the liquid is 0.8m, 0.5m, and 1.0 for gasoline, oil and sea water.1. find absolute pressure at depth 1.2m
2.find the depth at 1.8m
3. find the force F at depth 2.1m when diameter of drum is 0.5m
The barometric pressure reading at sea level is 760 mm of mercury while that on top 735 mm. if the density of air is assumed constant at 1.2 kg / (m ^ 3) ,calculate the elevation of the mountain top?
