  2. technical section
    this section had abundance of questions from communication(mobile n digital),microwave,waveguides n 8086.weightage from
    popular topics like analg,control,n/w,edc were low.this paper looked more like bel one rather than other psu's.i can't say abt others but if i have to prepare for a psu the topic which i would go for at the end would be communication,antenna,8086 etc. coz usually question from these topics don't come too often.although most of the questions were theoritical but some the options seemed really close.i would also be disappointed at noot seeing analog n n/w.so overall i can assess that technical can't be seen as easy walkover although some who have gone through stuff like comm.,antenna,8086 would find it moderate.so if some1 scores around 60(75%),i would say it is a very good performance.
    general awareness
    well this section was what i should say pretty nerdy.some real strange question like tagore n shakespaere 1 but that's gs afterall.20+ score would be good one n 25+ would mean that person had devoted good time to gs.
    reasoning and english
    most of the reasoning question were easy but some were real hard nut to crack.out of 24 question atleast 15-16 would be really easy and around 4-5 would be moderate with few tough questions.good score here would be around 20+.
    english passage can't be seen as an easy 1.few questions were really tricky as several options could have been the ans. so here 4+ would be a good performance
    overall 24+ in reasoning and english would be a good performance.

    3. no it is 100,both the cars travel 50m each in one hour total 100m,bird travel 100m in one hour.

    4. question was bird and car start simultaneously, when they meet together, bird comes back at the starting point and again from starting point, it goes to another side of the road, when they meet again bird comes back and the process goes on. what was the total distance covered by bird, until car reaches another point.

      Solutions is as follows:

      when bird and car starts, they meet at a distance of 66.67 m from left. means bird covered 66.67 m and car covers 33.33 meters.

      Now, bird comes back and covered 66.67 m again and car has total of 66.67 m only, but car has to travel 100 m.

      again the same process, bird covered 22.22 m and car only 11.22

      while returning back, bird covered 22.22 m and car only 11.22.

      after that bird covered 7.41 and car covered 3.70 m

      while returning back, bird covered 7.41 and car covered 3.70 m.

      again bird covered 2.8 twice (going and returning) and car covered 1.4 twice.

      again 0.9 twice by bird....

      totalling of birds is as follows: 66.66+66.67+22.22+22.22+7.41+7.40+2.80+2.80+0.9+0.9= 200 Kms.

  51. hi aap bole rhe ho.To reduce ISI sinc function is used but mujhe lagta hai ki BIT Stuffing is done dont know may be aap correct ho aur kisi question k answer mai daubt hai kya..please guys share ur experince.

  52. For Finance.... Cut off will be more than 100-110
    and there will be 3-4 marks of diiffernce between OBC and General. No idea about SC/ST.

    1. view factor concentric spheres- (R1 + R2)/R2

      rxnrate of exothermic rxn goes to maximum along adiabatic reactor.

      mixed flow reactor series 15 10 5 as conversion is directly proportional to V in case of CSTR

    2. sorry
      rxn rate of exothermic rxn passes through maximum along adiabatic reactor.

    5. The optimum size ratio for two mixed flow reactors in series is found in general
      to be dependent on the kinetics of the reaction and on the conversion level. For
      the special case of first-order reactions equal-size reactors are best; for reaction
      orders n > 1 the smaller reactor should come first; for n < 1 the larger should
      come first courtesy-octave levenspiel page no.-134

  57. view factor problem
    F12=1
    from reciprocity theorm
    F12*A1=F21*A2
    so F21=A2/A1
    F21=(R1/R2)^2

    1. one more qs on COD i.e. chemical used in the test of COD:
      both options KMnO4 and K2Cr2O7 are rite but K2Cr2O7 mostly preferd over KMnO4.

  60. Some more qs.

    By product of wet process for the production of phosphoric acid- Gypsum

    After absorption ammonia is removed from- Distillation

    catalyst used in the production of Nitric acid 97%- platinum/rhodium

    Heat engine efficiency and temp diff 60*C now given find the temp of heat source and sink- 325& 265*C

    For 1st order rxn in porus catalyst thiele modulus is 10 then effectiveness factor is- 0.1

    For gas phase rxn 2A-->B, feed consists 80 mole% A and 20 mole% inerts. if the conversion of A at the reactor exit is 50% then Ca/Ca0 at reactor outlet- 5/8

    A pulse tracer is introduced in an ideal CSTR at time t=0,time taken for the exit conc. of the tracer to reach of of its initial value- 0.693*t

    A batch adiabatic reactor with an initial temp. of 373K is used for the rxn A-->B. Assume heat of rxn is -1kJ/mol at 373K and heat capacity of both A and B is constant 50J/mol.K. The temp rise for the conversion of 0.5- 10*C

    Moles of Air used for complete combustion of C3H8-

    Molar composition of a gas is 10% H2, 10% O2, 30% CO2, and balance H2O. Now 50% H2O condenses then the final mole % of H2 in the gas on dry basis- 20%

    A pitot tube indicates 5cm of water when it is used for measuring velocity of air. velocity of air in m/s is- 28.2

    real gas approaches ideal behavior when- pressure<1 and Temp>1

    Rxn between Gleceride and Aldehyde- Transesterification

    An alkaline solution is used to reduce the conc. of CO2 in a stream from 10% to 0.1% by absorption with irreversible chemical rxn. The overall NTU based on gas phase is- 4.605

    Multiple effect evaporator has capacity to process 4000kg of solid caustic soda per day when it is concentrating from 10% to 35% water. The water evaporated in kg/day is- 27,500
