The specific weight of glycern is 78.6 lb/ft3. compute its density and specific gravitty. what is its specific weight in kn/m3

Explanation:

Specific weight is the amount of weight of substance present in a unit volume of the substance.It is given by :

= density of the substance

g = acceleration due to gravity =

Specific gravity is the dimensionless ratio of the density of the substance to density of water at normal temperature.

We have : Specific weight of glycerin:

1 lb = 0.4536 kg

1 foot = 0.3048 m

Density of glycerine =

The density of the glycerin is .

The specific gravity of glycerin =

Density of water =

Density of glycerine =

The specific gravity of glycerin is 0.128.

1 lb = 4.45 N

1 foot = 0.3048 m

Specific weight of glycerin is .

bcde is the incorrect answer it is a
