Assume that you have a bottle of 1Liter of Coke, then you agitate it, it will be pressurized, for the sake of the example, lets assuume 1.2 atm... Then you will open the bottle cap SLOWLY, letting the gas go out in a controlled manner, there is a lot of friction between the bottle cap and the outlet, this is what makes a reduction in pressure. In this case, the bottle cap is acting as a valve, you are controlling the flow of fluids.
Thanks for your explanation. Valve means controlled restriction on the flow path. This restriction will reduce the upstream fluid pressure, which will cause vaporisation. Just like flashing and cavitation in valves (undesirable) but in this case it is desirable for the vaporisation. Am I right?
Great explanation 💪
Thanks! Im glad you find it useful
I literally did the same edit in the figure f , y and (1-f) , x 😅😂
hehe great same minds think alike
hi, how a valve will reduce the pressure. thanks
