Fundamentals of Engineering one (June 2006)

a. Civil Engineering


1a. With neat sketches discuss any 6 structural steel parts used in construction
b. elaborate the requirements of good quality aggregates?
2a. Write notes on any 6 kinds of cement
b. discuss the Indian Standard Classification of bricks
3a. discuss the conditions in which pile foundations is adopted
b. Compare English bond and Flemish bond
4 . Draw the plan of the alternate courses of a one 1/2 brick thick English bonnd wall. Also draw the elevation. Make sketches of the typical bricks used and mark their dimensions
5a. discuss the main principles of surveying
b. With the help of sketches discuss the uses of cross-staff and optical square
c. discuss any 1 method of indirect ranging
6 . The subsequent consecutive readings were taken with the help of a Dumpy level. 2.550, 3.760, 3.900, 2.100, 1.870, 1.550, 1.250, 2.540, 2.050, 3.150. The instrument was shifted after the 3rd and 7th readings. The 1st studying was taken on the staff held on the bench mark of decreased levels 100.000m. Enterthe above readings in a level book form and work out the decreased levels of the point by height of collimation method



b.Mechanical Engineering


1a. Derive an expression for work done in an adiabatic process
b. A closed vessel containing 2Kg of carbon dioxide is at a temperature 20 degree celsius and pressure of 0.7 bar. Heat is supplied to the vessel till the gas acquires a pressure of 1.4 bar. Calculate: final temperature, work done on or by the gas, heat added, change in internal energy
2a. discuss the Kelvin-Plank and Clausius statements of the 2nd legal regulations of thermodynamics and prove their equivalence
b. A carnot heat engine recieves 50 KJ of heat per cycle from a high temperature source at 652 degree celsius and reject heat to a low temperature sink at 30 degree celsius. Determine the carnot efficiency and the amount of heat rejected to the sink per cycle
3a. Derive an expression for theair standard efficiency of Diesel cycle
b. An engine working on the otto cycle has a cylinder diameter of 150mm and stroke of 225mm. The clearance quantity is 1.25x10^-3 m^3. obtain the air standard efficiency. Take gama=1.4
4a. discuss the working of a 4 stroke C.I engine with a neat sketch
b. discuss with the help of a neat sketch, a plain carburattor showing idiling jet and choke. What is the function of choke?
5a. discuss the terms:i) saturation temperature ii) Wet steam
iii) super heated steam iv) dryness fraction
b. discuss the working of a Babcock and Wilcox water tube boiler with a neat sketch
6a. discuss the difference ranging from impulse turbine and reaction turbine
b. discuss the term 'compounding' in steam turbines. explain different methods of compounding steam turbines
