1)      The minimum water content at which soil is still in liquid state

2)    (0-3)- Nonplastic

3)    (3-15) - Slightly plastic

4)    (15-30) - Medium plastic

2) In pert the optimistic time is

There are three estimation times involved in PERT; Optimistic Time Estimate (TOPT), Most Likely Time Estimate (TLIKELY), and Pessimistic Time Estimate (TPESS). In PERT, these three estimate times are derived for each activity. This way, a range of time is given for each activity with the most probable value, TLIKELY.

3) Dengue weather is best controlled in which whether

4) Discharge is 80,000 cusecs and area is 1000 acres then duty will be

Duty = D (Acres/cusecs)

6)      Odour of water is removed by

Oxidation
Oxidation is the best method for controlling taste and odor problems. 

Aeration 
Aeration is a practical solution for taste and odor control when the problem is caused by volatile compounds, such as hydrogen sulfide. It is generally not the best method for controlling taste and odors that are caused by algae. 

Adsorption 
Adding powdered activated carbon to water or using of granular activated carbon (GAC) in the water filter can remove taste and odor. Powdered activated carbon (PAC) is the preferred method when the taste and odor is moderate and infrequent.

7)      Free board is actually

The distance between the level of the water and the upper surface ofthe freeboard deck amidships at the side of a hull: regulated by theagencies of various countries according to the construction of thehull, the type of cargo carried, the area of the world in which it sails,the type of water, and the season of the year.

8)      Gantt charts are used for

A Gantt chart is a horizontal bar chart developed as a production control tool in 1917 by Henry L. Gantt, an American engineer and social scientist. Frequentlyused in project management, a Gantt chart provides a graphical illustration of a schedule that helps to plan, coordinate, and track specific tasks in a project.

9)      Meandering depends on

10)                Why do rivers meander?

A meander forms when moving water in a stream erodes the outer banks and widens its valley, and the inner part of the river has less energy and deposits silt. A stream of any volume may assume a meandering course, alternately eroding sediments from the outside of a bend and depositing them on the inside.

9) Relation between G, S and e is

11)  To check the strength of sub grade

The California bearing ratio (CBR) is a penetration test for evaluation of the mechanical strength of natural ground, subgrades and basecourses beneath new carriageway construction. It was developed by the California Department of Transportation before World War II.

12)  Formula of uniformity coefficient

The uniformity coefficient Cu is defined as the ratio of D60 by D10. So when Cu is greater than 4 to 6, it is understood as a well graded soil and when the Cu is less than 4, they are considered to be poorly graded or uniformly graded. Uniformly graded in the sense, the soils have got identical size of the particles.

13)  Flexible pavements are designed by

A true flexible pavement yields “elastically” to traffic loading. It is constructed with a bituminous-treated surface or a relatively thin surface of hot-mix asphalt (HMA) over one or more unbound base courses resting on a subgrade.
