I think u make a mistake that consider this process is isenthalpic. The therm of pv changes sharply in this process

What are you talking about? If you have a constant supply of 15 Bar the entire System would have a pressure of 15 bar.
@dor312Ай бұрын
Let’s assume I have four valves connected in parallel. All the valves are supplied from a single source, and at the outlet, they merge into one pipeline. The pressure before the valves is P1, and after the valves, it is P2. If dP equals P1 - P2, then the system curve does not look like the one shown in the video. The greater the dP, the smaller the flow, and vice versa. Why is this the case?

A bit late to the party but is there a way to find the relationship between the decrease of differential head vs the flow?

Why preasure of discharge is greater than suction side ??? because of the diameter ,the diameter of suction greater than discharge diameter i cant underestand that but i know when diameter increase ,preasure increase and velosity decrease 😢

Anyone, please go to minute 5:43 I believe that A is the smallest pressure. B is bigger pressure. C is the biggest pressure. The explanation seems doesn't make any sense. Please anyone, if you have better argument or other video to convince about the correct answer. Thank you.

For some reason i always thought If one flow A is 15, and the other one B is 10, wouldn't the flow with higher pressure not "allow" the lower pressure to go inside C? How are they still able to mix? Am i making a mistake of treating liquids as having perfect flow?
@NomadUrpagi2 ай бұрын
Thanks for the enlightenment. For the longest time i treated pipe pressures like electrical laws and it kept confusing me: if A=15 and B=10 meet, shouldn't the point C be either a sum, a difference or the average? Turns out line losses are huge and the result is determined by if the outlet is open or closed

If I have LPG Tank as supply reservation and three multistage centrifugal pumps installed on common manifold together as a one or two working together to provide me with Q more if run one pump, put when I operate 3 pumps the flow decreased to a very low level to stopped completely. Can you interpret or explain it why? Thank you

Maybe for a new video, you could explain how you would size a valve on the 8 inch pipeline to regulate the flow and pressure to your friend that needs the 1 bar😊

What costs more, an 8 inch pipeline of 15 meters or a pump with any other of the smaller diameter pipelines?

Okay, great. But what will happen to the shut-off head in case you increase the suction pressure? For example, if there is a pump with a suction pressure of 0.2 bar and a discharge pressure of 9.5 bar, and the shut-off head is 10 bar, what will happen to the pump shut-off head when you increase the suction pressure to 1.5 bar? Will it increase or remain constant?

AC is just a heat transfer system using some substance that can boil inside (absorb heat) just above boiling point of water and condense outside (give up heat). No such thing as cold only less heat. Heat always moves from hot to less hot
