as water is flowing to the right force exerted by pipe on water should be left to right=its perhaps helping the water to maintain the flowfoo9008 said:
if so , why F2 is in opposite direction ? according to you , F2 should help the water to flow , so it should in the same direction as the water flow , right ? which is directed to the right ?drvrm said:

i still don't understand why the F1 is acting as the same direction of the low of water , can you explain further?drvrm said:
or do you mean since the diameter is decreasing along the pipe , so the F1 is to help the water flow (since there is not much obstruction ) , F2 is the force which try to prevent the water flow (since the water is difficult to move thru smaller diameter of pipe), so it is in opposite direction?drvrm said:
the link doesn't explain about F2(force at the exit) alsodrvrm said:
the second link discusses reducer and forcesfoo9008 said:
Why F1 is behind the control volume? F2 is ahead of control volume?Chestermiller said:
If there is pressure within the fluid, the fluid behind exerts a forward force on the fluid ahead of it, and the fluid ahead exerts a backward force on the fluid behind it.foo9008 said:
Why, can you explain??Chestermiller said:
Are you aware of Pascal's Law that, at a given location in a fluid, pressure acts equally (isotropically) in all directions?foo9008 said:
Yes, how is the condition above link to pascal lawChestermiller said:
Is there pressure in the fluid that is situated behind the fluid in the control volume? According to Pascal's Law, does it push forward on the fluid within the control volume? Is there pressure in the fluid that is situated ahead of the fluid in the control volume? According to Pascal's Law, does it push backwards on the fluid within the control volume?foo9008 said:
The force on a pressure pipe is the amount of external pressure or load exerted on the pipe, which can affect its structural integrity and ability to withstand pressure.
The force on a pressure pipe is typically calculated using the formula F = PA, where F is the force, P is the pressure exerted on the pipe, and A is the cross-sectional area of the pipe.
There are several factors that can affect the force on a pressure pipe, including the type of fluid or material being transported, the velocity of the fluid, the temperature, and the diameter and thickness of the pipe.
To reduce the force on a pressure pipe, the pipe can be reinforced with additional support structures, such as struts or braces. Additionally, using a larger diameter or thicker pipe can also help to distribute the force more evenly.
If a pressure pipe is subjected to high force, it can lead to structural damage, leaks, or even bursts. This can result in costly repairs, downtime, and potential safety hazards. Regular maintenance and monitoring can help to prevent excessive force on pressure pipes.
