How pycnometer measure specific gravity?

Procedure.

  1. Weigh the empty and dry volumetric flask / Pycnometer to the nearest 0.01 gram and record the weight as W1.
  2. Take about 100 grams of oven dried soil and put it into the Pycnometer.
  3. Now weigh the Pycnometer and dry soil to the nearest 0.01 gram and record the weight as W2.

What are the parts of pycnometer?

The pycnometer is a glass vessel of a special shape, the lower part 1 of which is spherical, the upper part 2 is also spherical and connected to a vertical cylindrical tube 3, on which there is an annular horizontal mark 4, Between the two parts of the pycnometer 1 and 2, separating it in the diametric in half the …

How does a gas pycnometer work?

A gas pycnometer operates by detecting the pressure change resulting from displacement of gas by a solid object. Expanding a quantity of gas at known pressure into an empty chamber and measuring the pressure establishes a baseline. Then a sample is placed in the chamber and the chamber is resealed.

What is the size of pycnometer?

Ertco Pycnometer, 11.5 mL capacity, 1/8″ (3.2-mm) hole in lid.

What are the applications in geotechnical engineering where the specific gravity is used?

It deals with the method of test for determination of specific gravity of soils which finds application in finding out the degree of saturation and unit weight of moist soils. The unit weights are needed in pressure, settlement and stability problems in soil engineering.
