NTPC Placement Paper Whole Testpaper new Delhi-11 Apr 2009
hi friends, I am abhinav B.Tech MECH. I appeared for NTPC written test on 12th april held on all India basis. here i am giving the questions as many i remember: the paper consisted of 2 sections-120 technical and 50 questions on general aptitude. the aptitude section consisted of questions from english & aptitude. There were no questions from General knowledge. SECTION 1 Q1 stress = load/ area Q2 deflection in simply supported beam in case of UVL Q3 definition of cantilever Q4 relation between elastic constants E=2C(1+1/m) Q5 if stress is applied at free end of cantilever, then where is chance of breakage Q6 which type of turbine is francis turbine Q7 relation for unit discharge of centrifugal pump Q8 relation for specific speed of pump Q9 direction of flow of water in axial flow turbine Q10 what is deformation per unit length called? Q11 Hook's law is applicable upto- elastic limit Q12 design of thin cylinder is based on- Q13 Lame's theory is used for thick or thin cylinder Q14 Unit of thermal conductivity Q15 basic law of heat transfer Q16 effect of supersaturation in nozzle on entropy Q17 definition of nozzle efficiency Q18 what is measure of performance of refrigerator Q19 definition of heat engine efficiency Q20 in nozzle potential energy is converted into kinetic energy Q21 Which type of mechanism is Watt indicator mechanism Q22 The value of stress in suddenly applied load Q23 Venturimeter is used for measuring - rate of flow in circular pipe Q24 Which uses consumable electrode- TIG/ MIG Q25 Water insect walks due to - Surface tension Q26 What is stress / strain- modulus of elasticity Q27 what is the direction of Coriolois component- perpendicular to slider velocity Q28 if velocity of A & B moving in opposite direction are w1 & w2, then the relative velocity- Q29 ratio of stiffness when springs are connected in series to that connected in parallel Q30 equation of length of compound pendulum Q31 definition of kinematic similarity Q32 what is maximum temperature of oxy-acetylene flame Q33 profile satisfying law of gearing Q34 flexible method is used for Q35 effect of L/n ratio on secondary force in engine Q36 which cycle is used in SI engine Q37 effect of buoyancy is based on - arcmidise principle Q38 rise or fall of liquid is based on - capillary effect Q39 definition of stable governor Q40 gas used in fire extingusher Q41 which is used as refrigerant- freon Q42 definition of metacenter Q43 use of draft tube Q44 equation for power transmitted by belt drive Q45 closed cycle gas turbine works on- brayton cycle Q46 what is primary work of compressor Q47 question on pascal law Q48 Ist law of thermodynamics is based on conservation of energy Q49 continuity equation is based on there were many questions on production tech also. SECTION 2 it consisted of 4 q on articles 4 questions on prepositions 4 questions on synonyms 4 questions on antonyms 5 questions on reading comprehension 5 questions on bar chart rest were mathematical & logical reasoning. I had attempted 88 in Ist section & 43 in 2nd section. I had cleared the written test and got a call for GD & interview on 9th july at PMI, Noida. the interview were going on since 1st june. I could not clear the interview round. But i will try next time. for any information u can contact me at my mail id ABHINAV.ARIES4271@GMAIL.COM. ALL THE BEST TO ALL OF U.
