14.21 Density measurement function (option)
This function allows for determination of solid body density, upon the basis of
weight in the air and weight of material immersed in liquid of known density,
according to the formula:
m1
ρ = * ρ liquid
m1- m2
where:
m1-mass in the air
m2-mass in the liquid
The measurement consists of two phases:
Phase I – solid body sample measurement in the air
Phase II – measurement with immersion in the liquid
This function also allows for determination of liquid density, upon the basis of
plunger weight (with known density) in the air and tested liquid. The following
formula is used:
m1 - m2
ρ =
V
where:
m1-plunger mass in the air
m2-plunger mass in the liquid
V – plunger volume
The plunger volume is indicated on its hanger.
This measurement also takes place in two phases:
Phase I – plunger measurement in the air
Phase II – measurement with immersion in the liquid
More comprehensive description is delivered with the Hydro Set.
