Looking through the second solution sir, the formula portrayed. I.e. the part of A1/A2, why was diameter used in replace of the Areas of bothsides. Because calculating the area and making use of it in this formula the answer will definitely be different sir. Also, at the "Q", in the formula where density is, the density on the question was again not used. But instead 1x10³ was used, why is this sir?
No. If you used the area rather than the diameter, you would arrive at the same answer. Try it and see. As I explained in the video, since we have a ratio of areas, the diameter can be used as other parameters in the ratio will cancel out.
@@electro_teachI did sir, very carefully the answer are different sir the area of A¹ is 0.00302m², while for A² is 0.0095m² Dividing this two you get 0.3178 the square the answer you get 0.101, subtracting 1 from it base on the formula you get 0.899, then square root the answer you get 0.9482 sir. Not same with what you are having sir
Sir, in getting the differential pressure of the upstream to throat Based on the formula used Q=CEBA¹√2∆p/density, What is "B" for as i noticed you used 1 as B, mean while it was not stated in the question is it a constant value sir, or it changes
The soln to question no 3i finding the REYNOLDS NUMBER, the p stands for the density of the and the density is 103kg but you used 10^3 as p how and that is not given in question Or is it a constant value?
Sir, when you were solving the Reynold's number after getting the velocity of flow (V). The diameter to use next to get the Reynold's number should have been the diameter of the pipe given which is 110mm. But instead you made use of the the throat diameter, that we have use in calculating the area of throat (A). Why sir? And also the density of fluid was given which was 103kg/m³, but you used 10³, why sir?
Excellent teaching
Glad you think so!
Wow superb
I really this video
Thank you sir
Good job sir
Excellent
Thank u sir
You are amazing
Thanks for the solution sir
Thanks Sir
Thanks for this sir
You’re amazing sir
Thank you kindly.
Thank you sir ❤

@@electro_teachbut I did, didn't arrive at same.
@@fieldsofcomedy You need to do it again carefully.

It's a constant.

Or is it a constant value?
It was a typo. It's not p but density (Greek letter, rho).
In that raynolds number formula... How do we get that p? It's some how confusing sir
Sorry about that. There was a typo error there. It's not "p" but the Greek letter rho which stands for the density.
This is really helpful !
Glad you think so!

The throat diameter is the right value to use. The 10³ and 103 might be a typo. I will recheck that.
@@electro_teachum🤔 but why not the diameter of the pipe sir.
Excellent teaching
Thank you sir
