Question

A Test was Performed according to the following data:

Volume of specimen, V = ? = ?? 2 L (cm2 ) .	418.03
Specific gravity of soil solids, Gs	2.66
Mass of specimen tube with fittings, (g)	238.4
Mass of tube with fittings and specimen, W2 (g) Dry density of specimen,	9365
Void ratio of specimen,	0.53

(Note: pw = 1 g/cm³

If K=QL/Aht (cm/s) and Gs =2.66 , Volume of Specimen is 418.03 cm³

Determination of coefficient of permeability

test number	1	2	3
average flow >>Q(cm3)	363	373	393
time of collection, t (s)	63	63.3	61.03
Temperature of water, T (C)	25	25	25
Head difference, h (cm)	60	70	80
Diameter of specimen, D (cm)	6.33	6.35	6.33
Length of specimen, L	13.2	13.2	13.2
Area of specimen,A	31.67	31.67	31.67
k=
average k=

K₂₀

Find out the Magnitude of K

mention of the source of error in this test

What is the type of soil in this test

what are the maximum and minimum diameter of soil used in this test as you expected ?

Clear solution please
