@@PhysicsRoxz I meant in the tube, and the design would be containing just 2 holes in tube and you have to add oil and water no additional equipment only tube two holes from above a stand and a mass at bottom to hold the tube in shape
In this case, the air (compressible fluid) is used to compress the water in manometer, so there is a chance of error in actual pressure. Am I right, if not, please correct me.
Actually yes, you're right. The compressed air will actually affect the water pressure. In this video, I only talk about the liquid pressure because this is what is covered in the school syllabus.
Wrong. When you push the tube down in the glass of water, the pressure of water doesn't have an effect on the height difference in the tubes. What makes the difference is the fact that you are compressing the already existing air in the tube that you are pushing into the water. The volume of it decreases and so the pressure of it increases and then the height difference in the tubes appears. If the height difference in the tube was caused by the water pressure of the glass, the height difference in the tubes would be the same as the depth of the glass water, which isn't. I experimented this today.

Very nice, Thanks and Good luck for your TH-cam channel
Thank you for your kind comment! You have a great channel too!
Thanks mam love from India 🇮🇳
It helps me a lot thanks!
You're welcome! I'm glad that this video was helpful to you
can you please explain briefly, what if two liquids added are water and oil
Hi, do you mean if we add two liquids in the tube or in the cylinder?

Does this video answer your question? It's a video about just the tube and liquids.
