Does humidity effect the density of air? | Notes and ...

While density of air means the mass per unit volume of the atmosphere of the earth, which alters with the change of temperature and humidity of the atmosphere. Presence of humidity in air makes the condition hot and humid. Density of air (and air pressure) is less in places of high altitude.

How do you calculate density and relative density?

Relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.

Dec 03, 2004 · While the SPT is related to relative density, there has been much correlation done with the small dynamic cone penetrometer (Sowers Method) and in-place density. This should be done as a site-specific correlation due to the variable nature of soils, and really only works well in the upper 5 to 7 feet because of manual equipment handling.

What Is the Formula for Relative Density? | Reference

The formula for relative density is the quotient of the mass of the substance divided by the mass of the reference substance. The relative density can also be determined by finding the ratio of the weights in place of the density.

Relative Density and Absorption - ce.memphis.edu

Relative density is the mass density of an object relative to the mass density of water (also called specific gravity). Relative density depends on the volume you assume for the aggregate particles. An aggregate sample has an oven-dry mass of 3954.2 g, an SSD mass of 4006.8 g, and a net volume of 1532.6 cm3.

DENSITY UNIT CONVERSION CALCULATOR

Density is the mass of material per unit volume. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 oC. Because specific gravity is a ratio, it is a unitless quantity. For example, the specific gravity of water at 4oC is 1.0 while its density is 1.0 gcm-3.
