Question

What is density test?​

Answer 1

!! RAM RAM !!

ANSWER ==

Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. The volume of objects can be worked out by multiplying height by length by width.

hope it helps uh ❤

Answer 2

Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. The volume of objects can be worked out by multiplying height by length by width.

There are two basic test procedures- Method A and Method B. The more common being Method A, can be used with sheet, rod, tube and molded articles. For Method A, the specimen is weighed in air then weighed when immersed in distilled water at 23°C using a sinker and wire to hold the specimen completely submerged as required. Density and Specific Gravity are calculated.

Specimen size:

Any convenient size.

Data:

Specific gravity = a/[(a + w)-b]

a = mass of specimen in air.

b = mass of specimen and sinker (if used) in water.

W = mass of totally immersed sinker if used and partially immersed wire.

Density, kg/m3 = (specific gravity) x (997.6)
