Question Paper
1. Attempt any four of the following:
Distinguish between method ofjoints and method of sections. Which is the appropriate method for influence lines
Illustrate the method by constructing the influence line for the force in a diagonal member of Pratt truss with
inclined top chord members.
Write short notes on consolidated quick tests on sands and critical void ratio.
Derive the condition Q2/g What type of flow condition is indicated by this equation
State Abram's law. Describe how both strength and workability can be ensured in concrete mix.
Write Short note on reciprocal levelling.
Briefly describe any two turbidity tests for drinking water.
2. A symmetric, three hinged parabolic arch of span and height carries a concentrated load at a distance of from left support. The moment at a section distant hom the left suppOli is zero. Derive the value of in terms of hand x.
Derive an expression to obtain depth of embedment of cantilever sheet piles in cohesive soils.
3. An earthen bank embankment is to be constructed for an important highway. Explain briefly what preliminary investigations are required with regard to
(i)selection of embankment materiaL
(ii)selection of proper procedure or construction.
List the tests to be done for quality
Two pipes each of length and diameters D1 and D2 are arranged in parallel.When total discharge Q flows through them,the head loss is h1.If the pipes are in series and total discharge is Q,the head loss is h2.If D1=2D2 and h2= 10m.Find the value of h1.Neglect minor losses.Friction factor is same for all pipes.
4. A T section of mild steel has the following dimensions:
Total depth=9cm.Breadth of flange=8cm,Thickness of flange and web=1cm.Calculate the plastic moment of the section if yield stress is 2500 kg/cm2.
If stream function for steady flow is given by si2.Determine whether the flow is rotational or irrotational.Also determine the velocity potential.
5. Explain the concept or a two stage digestion system and why It IS required. Describe the salient features of this type or sludge digestion.
A water course commands an area of 800 hectares. The intensity' of irrigation of rice in this area is 50%. Transplantation of rice crop fakes 15 days during which period the water depth required is 60 cm. Rainfall during this period IS 15cm .
Find out: Duty of water for transplantation . period.
Duty at head of distributory, taking 20% loss in water courses.
Discharge required water courses.
6. Explain the difference between milestone chart and bar chart. How can a mile stone chmi be developed into a network?
Three activities to be implemented 111
parallel have the following time-cost
relationship A B c
Activity
Time, days 10 dayS} II dayS} 7 dayS} Rs. 800 Rs. l,200 Rs. 500
Cost 9 dayS} 10 dayS} 6 dayS} Rs. 900 Rs. 1,350 Rs. 700 8 days 9 dayS} 5 dayS}
Rs. 1,000 Rs. 1,500 Rs. 900 What will be the feasible range of total direct cost for the three activities
together?
7. Briefly describe the characteristics of a good brick. List any three types of defects in bricks and indicate the causes of these defects. Explain, why is provided in bricks. What are modular bricks?
