🙏🏿Thank you very much sir and also for using English. I have been hunting for this tutorials on KZbin the whole day and yours is the best. I have just subscribed and hopefully fluid dynamics will now be easier.

[@vincentkennedymcmahon50]

Lol are u from integral university

[@SeekTheTruthAndTruth]

Sir, how come you got the value of angle from equations involving already two unknowns?? Pls clarify.

[@chahatsharma2231]

Bro take ratio of Fy and Fx that is ratio of two equation and equate to Fy/Fx that is equivalent to tan theta and try to solve it, it is easily solvable in that manner

[@anshchauhan7979]

@@chahatsharma2231 If we go by this way what we will put p1a1/cos theta

[@bleubluebleu]

The value of theta is usually given in the question itself. The tan theta thing is entirely different, it fetches us the direction of the resultant of the reactive forces.

[@kumarvermakri]

@@anshchauhan7979 would you provide this theeta calculation

[@anandsingh-mp4zv]

3 unknowns 2 equations, impossible to get theta... It must be given in the question it self, afterall theta is a design parameter and it should be known before the problem. Note: tan (angle) = Fy/Fx, here angle is not the same theta as that of pipe...

[@davidwang1372]

You are not wrong, the instructor was wrong. Bend angle should be given

[@yusuffabdulmusawwir6807]

Our lecturer just gave us a question like this and the bend angle was not given 😂

[@yusuffabdulmusawwir6807]

Plus I didn't get the part when he said we'll divide the two equations, are we going to just for get fx and fy when dividing?🧐

[@matthe6114]

it s a really good video, i was really thinking about clikking or not, cause his accent is hard to understand, but after his explanation, i think that he s a way better than my prof.

[@nickfleming3719]

What is the independent effect of the bend on fluid flow if the diameter does not change? The flow rate cannot change, and the diameter is the same so the velocity wouldn't change. So it has to be a change in pressure right? Since the fluid is changing direction, that means it is accelerating and therefore there is some energy transfer. Could you explain the energy transfer process that takes place? thank you

[@ankurghosh2387]

You asked the wrong person dude. He's just a copy paster I've seen his previous videos and it lacks the basic fundamental explanations

[@adarshsingh4974]

*CORRECT THIS* 6:16 u can't take cos(theta) common from the numerator so u can not get value of theta

[@nageshwarsingh1044]

Sir plz explain how you calculate thita..bcoz cos is not coming out common..

[@anilkumarlopinti5313]

i think we cannot get angle theta here.bend angle theta is different from the angle made by the resultant of Fy and Fx. the ratio of Fy and Fx gives angle made by the resultant but not the bend angle. if i am wrong please help me

What if the was an elevation, of like a metre, does it count or do you remove them?

[@makedreamscometrue465]

Is it for jee

[@kbbro]

Sir what can we do when only one diameter is given in the question

[@bhan4]

Mass flow rate is same as other side m1 = m2. So, rho*v1*A1 = rho*V2*A2. With this I think you can get the diameter.

[@vincentkennedymcmahon50]

Probably some other Data would be given like discharge

Hi sir thank you for your presentation I am watching your courses continuously but I note two error in numerical calculation for the forces Fx and Fy the correct result is As follows : _2704.604494 AND 24869.04479

[@yusuffabdulmusawwir6807]

This question has insufficient data..... The same question is given in book fluid mechanics by Dr.R.K.Bansal. 2012 edition,refer page no 237and problem no7.12.

[@tireniagboola5708]

Thank you. This was very helpful, I was able to locate the material and follow up with the complete question. Though it was on page 287 problem 6.29 of the version I checked

[@MECHANICAL_BUDDY]

Sir, Your value of theta is wrong..it is 45° but your value of the forces is correct...cuz you have substituted 45° in the equations...plz cross check once again

[@modassirahmed5712]

You didnt show how you got theta

[@hasibmahmudridoy5078]

Best

[@nkuleskhona2322]

Still not happy about the equation of Fx, the laws of maths say when one crosses the equal sign change a sign so here it seems that is not the case

[@nehalpramod007]

Its not the fx which is considered here,the reactive force of fx..that is.. -fx is taken while writing the eqb eqn..
