Hello. I work for a company and I need your help! The pipe is welded to the wall. However, the worker applied force to the right with the force of F, and the welding was cracked. As a countermeasure, welding is carried out in two layers as shown in the picture on the right. In this case, is it...

I'm sorry for the lack of explanation Assuming that pipe B is pulling pipe A with the force of F1, I wonder if the force of F2 is the same as F1 if the length of pipe A is extended and installed above the same line as shown in the figure.

Hi. I need your help! I have a college physics question Suppose there are pipes A and B. [Figure 1] I had to connect pipe B to pipe A, but pipe B was short, so I bent A by about 30 degrees and installed it. [Figure 2] It's a picture of the pipe A being installed by increasing the length in...

Hi. Thanks for your help. If it is assumed that it is normal air, not incompressible, can the Inlet and Outlet flow rates be different if the pressure drop is large?

Thank you for your help every time. It seems like you're learning a lot. I accidentally didn't put a condition on it. condition It's the same as Q2=Q4. Theoretically, the case of ideal fluids seems to be Q1=Q3. I think it's Q1>Q3 when I think about the straw. I'd like to prove the content with...

Hi. Since I've been studying fluid mechanics, I've been asking a lot of questions Thank you all for your help! I suddenly have a problem that I want to think about while studying today. I would like to know the change of air volume according to the pipe shape as shown in the picture below...

Wow! thank very much!!! Thank you for your detailed explanation. I understood it perfectly when I expressed it in a formula like this.

There's something that's hard for me to understand. Assuming an incompressible fluid is flowing, friction would reduce the static pressure. Is there a moment when the length of the pipe is infinite and the static pressure becomes zero? I wonder if the dynamic pressure would decrease at that time.

I'm sorry for the late response because it's Korean time. Yes, that’s right. Assuming that it is a pipe that descends vertically, and that the lower fan rotates to draw air from top to bottom (at low speed, close to incompressibility), I would like to prove how the inlet airflow Q1 and the...

Thank you so much for the CFD interpretation I understood that very well. I'm sorry, but let me ask you one more question. I understand m1=m2, but is it a part that can be proved by the Q1>Q2 hydrodynamic formula?

Thank you for your detailed explanation. :) After studying the concepts of static pressure and dynamic pressure, I came to understand them. Then, because the length of L is infinitely long, does the dynamic pressure energy decrease from the moment the static pressure energy becomes zero? And if...

Hello I need your help studying hydrodynamics. I have a question about the volume of air. Assuming incompressibility, non-viscosity, there is a coefficient of tube friction, and it moves in laminar flow... The Oulet stage Fan is installed, so air moves from top to bottom. The cross-sectional...

Hi! I have a loss head question. There is a difficulty in understanding the hydrodynamic loss head concept. Assuming that there is a one-sided tube with incompressibility, visibility, tube friction coefficient and cross-sectional area A.. There is friction in the loss head formula, but is the...

Hi. I am Hauzen from South Korea. I came here to gain a lot of engineering knowledge from this forum. I want to be a competent engineer with a lot of your help. I look forward to your kind cooperation :)
