Which of the following gives the correct increasing order of the densities of a soil sample Mcq?
47. Which one of the following, gives the correct decreasing order of the densities of a soil sample?…Discussion :: UPSC Civil Service Exam Questions – Section 13 (Q. No. 47)
[A]. | Saturated, submerged, wet, dry |
---|---|
[C]. | Saturated, wet, dry, submerged |
What is submerged density of soil?
Submerged density or bouyant density is the density of a mass of soil as observed under water in a saturated condition of course. It is calculated as the difference of the soil density in air and the density of water, divided by the density of water.
Is Wet density higher than dry density?
The relationship between dry density and wet density is: dry density = wet density divide by (1 + moisture content as a fraction). e.g., Moisture content is 10\%. Wet density is 110 pcf, then the dry density is 110/1.1 = 100 pcf.
What is the relation between E and N?
Void ratio (e): Void ratio is usually defined as the ratio of the volume of voids to the total volume of soil solid. Porosity (n): Porosity is defined as the ratio of the volume of voids to the total volume of the soil.
Which of the following method is most accurate for the determination of water content of soil?
Oven dry method
Oven dry method is the most accurate and simplest method for water content determination. In this method complete drying of soil sample occur and water content in sample is calculated accurately by a maintained temperature in the oven ( 105° C to 110° C) for 24 hours.
Which of the following gives correct order of increasing densities?
Air < Oil < Water < Brick. The mass per unit volume of a substance is called density (density = mass/volume).
Which of the following gives correct increasing order of acidic strength?
Detailed Solution The correct answer is Water < Acetic acid < Hydrochloric acid. The increasing order of acidic strength can be represented by Water < Acetic acid < Hydrochloric acid.
How do you calculate submerged density?
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
What is wet density?
The density of the sediment is determined by its composition. The phial is then re-weighed and the weight of the sediment divided by 2 to determine the density as grams per cm3. …
How do you solve for wet density?
The wet bulk density will be the total mass divided by the total volume. The solid mass is 375 kg and the mass of the water is 0.15 * 375 = 56.25 kg, for a total mass of 431.25 kg. So the wet bulk density is 431.25/0.75 = 575 kg/m^3.
Which is the correct relationship between voids ratio E and porosity N )?
Question: The relationship between void ratio (e) and porosity ratio (n) is : 1 n = 1 + e 1 − e n=\cfrac { 1+e }{ 1-e } n=1−e1+e.
What is the saturated and submerged density of soil?
Submerged density of soil mass = 0.5 (saturated density of soil mass) For example- most soil has saturated density nearly 2 gm/cc, wet density 1.7 to 1.8 gm/cc, dry density 1.5 to 1.6 gm/cc & submerged density nearly 1 gm/cc.
What is the difference between wet soil and dry soil?
In wet soil, voids are partially filled with water hence mass of wet soil is less than saturated In dry soil, voids are filled with air only hence mass of dry soil is less than the wet & saturated. now saturated density (saturated soil mass) > wet density (partially saturated soil mass) > dry density (dry soil mass)
What is the difference between bulk density and dry density?
A soil is a complex three phase system – comprising of soil solids, water and air. Bulk density (aka total density) is the total mass of the soil (ie mass of soil solids, water and air) per unit volume, while a dry density is mass of soil solids only per unit volume of the soil.
What is the correction for Stoke’s law in hydrometer analysis?
63.When the hydrometer analysis is performed, it requires correction for 64.According to stoke’s law, the velocity at which grains settle out of suspension, all other factors being equal, is dependent upon 73.The Uniformity coefficient for a uniformly graded soil is nearly unity.
