Thats all I remember

MECH 15 evening….no of orders was askd ans: 50

i think in cantilever problem slope is pl/EI

in q no 32 boundary layer thickness is inversely proportional to underroot x

in q no 17 i got 638.5

in q no 7 ans is 50

i got effectiveness of heat exchanger =.66666

1.slope my ans is right chesk the units

2.for 32 u r right

17. Ft comes out 300 N

7. ya its 50.

n effectiveness is 0.67

dude boundary layer problm…boundry layer thickness is proportional to underroot x only not inverse according to blasius as well as vonkarman in laminar flow.

yup BL is directly proportional to sqrt of distance

bhai thts..hX=(RYNOLDS NO)^.5*(PRANDTL NO)^.666 ISSE HOGA..

but my ft comes out tobe 600 N and in aptitude question flow should be i think 2.5 times

ans of trapzd is 1.80875

ans of trapezoidal is 1.7533

Thats right same answer here.

Thank you for ur reply. If anybody wish to discuss ME evening session on Whatsapp..

9405170329 this is my number. I will definitely give reply to you.

The question to find the bolt… I think it should be M12… because ur calculation gives core diameter and specification is based on nominal dia…therefore it should be core dia/0.84.

yu are right ans is M12

height gauges are used to measure distance where as autocollimator can be used to measure angle and deflection

Can u plz upload ME evening session answer key 15 feb

plz upload ME answer key

Please send answer key 15th after noon

mangesh que. no.34

ans=144

33. your answer to the surface tension problem is correct.

21.Could u pls post the question no 21.

the question has diagram ,one has tension and shear in same plane and other figure has tension and shear in different plane

in surface tension problem

they talk about air bjbble so formula is

6(sigma)=pd/8 so ANS IS 144pascal

4(sigma)/d = surface tension in an air buble……………..check out at wiki also…..

hey plz tell me one thing eigen values were asked or eigen vectors

It was eigen vectors [1 1]

for soap bubble it is pd/8.. but for air bubble it is pd/4

fin effectiveness is correct=0.667

pressure drop=6028

thermal conductivity is absolutely correct=0.1

Guys discuss more and more question so there wont b any need of Solution key

Im going to give hint regarding question plz do tell question or answer..

39.red yellow blue green light on step

40.item no.5 (pie chart)

41.sum of odd and second highest even number(share both the numbers)

42.match the pair – defects-blister

43.match the pair – G02 G03

44.match the pair- m/c process milling – slotting

45.break even analysis (table was given)

46.square hole 10×5 mm .. shear force was asked

47. square hole in m/c process – EDM

48.min function value -> exp(-x)*sin(100x)

49.crashing value CPM – share formula

50.torque transmitting problem using uniform wear theory

51.VCC enthalpy valculation

52. Gate 2014 balloon with helium inside it

53. max blade efficiency

54. Radiation problem of hemisphere

55.Effectiveness 0.67

56.calculating enthapy when internal energy and WD is given

for baloon ques i did by pv=mrt and tension = mg

square hole by EDM

minimum function question is from laplace..we have to do it by integration

min value qu. how it is from laplace

actually he said x greater than zero so we have to integrate it

then limits 0 to infinity……………..we have s value 1 so lalace of sin100x

inplace of x as t…

so what is the answer finally

how square hole is by edm??explaination please..

work piece material was not given n EDM is for elect condctng mtl only…. so i think ans is plasma cutting

how would tension be equal to mg??

how many questions did u attempt…n how many marks are u expecting mangesh.???

im expecting 60+

azeem ur most of answers r correct u will definitely score 70+…. all d best.. n plz keep discussing questions

did you remember the qn of turbine and heat pump that was asked ans of machining time was 1.5 mins

For 41, it is 153 and for 56 it is around 3100. (Not sure)

i dont remember exactly by numbers are 71 n 88 around

max blade efficiency impulse turbine ka tha ki raction turbine ka?????

i use (cos 20degree)^2 formula……………is it right or wrong???

57.dy/dx=cos(x+y) wala..

58.flywheel question for finding moment of inertia or mass..

polar moment was asked in problem ie izz

gate14 baloon qn..i think 5828 N (not sure bt it was 5000+)

flywheel value of alpha.. 0.5625

in a qn EOQ was asked 2000

truck on 10 degree slope accln 2.2125

maths curl of F ans is A

Punching force 300 KN

are u sure about EOQ..n how do u calculate alpha..

in the flywheel mass was equally divided btwn outer rim and central disc and rad of dics was R/2…so have to take M/2 means disc- (MR^2)/2 RIM – MR^2 is genrl exprsn. so here

DISC- {(M/2)*(R/2)^2}/2 + RIM (M/2)*R^2 = 0.5625 MR^2

How it is M/2.. n sorry i don’t remember marks for each qu.

maths curl ans is B

punching force 300

pie chart ans is C

red yellow blue balls in stair ans is C

15th feb afternoon

EOQ 2000

m+n-1

both link rotate

english fill in the blank ans is EACH(not sure)

odd plus seccond hightest even ans is 163

squere root of k1+k2/ m

deflection pl^4/8EI

thermal stress zero

math limit .5

eigon vector ans is D {1,1}

trapezoidal 1.75(not sure)

mc time 1.5

i think EOQ was 2000 n i hve read answer posted somewhere. and Mangesh plz mension marks for the questions wrt question number u posted.

bcoz mass of flywheel is M and it is equally divided btwn rim and disc so M/2for disc and M/2 for rim

for que.41 sum of smallest odd no. and second largest even no .

Answer= 163 (75+88)

Yes u r right

answer to question 46 is 450 kN

Using formula Stess=(Force/area)

Area=perimeter of rectangular slot*thickness

Plz send 15th evening answer key

I think that ans of sin100x should be ’9′ after putting 9 it comes to 0

u can put zero too

answer is zero or …or we have to do by laplace..

plz remind me in detail q no 46 and 51

send me gate 2014 me ans key of 15th feb of evening session

15 feb eve session answer key chahiye chutiyo

Plz send me the ece 15 afternoon session question and solution

in a clutch question ,is there any effective surface

no

what is formula for hemisphere problem

maddy, in hemispherical furnace problem shape factor i got was 0.5 and bcoz total heat interaction was asked i think formula was — S-B const*(T^4 – t^4) / thrmal resist…

In the helium balloon problem, we do take inside He pressure and temp equal to given outside air press and temp, right?

yes………….

i calculate the weight of displaced air…….

inside He pressure = outside air pressure ????

RIGHT…

In that red, blue green ladder question, we were asked the incorrect statement, and all seemed to be incorrect to me.

Actually in question it was asked that which is not necessarily correct

yeah and it seemed none was necessarily correct..!

as far as i remember last option was not necessarily correct would you post the exact question so that i can elaborate more..

pls disscuss 15 morning me paper
