Explaining Water Flow: Inlet vs Outlet Pressure

In summary, the conversation discusses the pressure at the inlet and outlet of a pipe with constant volume rates and no friction loss. The question asks whether the pressure at the inlet is equal to the pressure at the outlet, and the response suggests looking up the Bernoulli equation for an explanation. The final statement reiterates the belief that the pressure at the lower point is higher, and asks for confirmation.

Homework Statement


this is a pipe where the water flow from low to high. assuming no friction loss (volume rate are constant at both inlet and outlet) , is the pressure at inlet = pressure at outlet ? p/s : inlet and inlet diameter are same

Homework Equations

The Attempt at a Solution


my question is no ... because the outlet is somehow higher than inlet . can someone explain , please?

Look up the Bernoulli equation, an energy balance that deals with this kind of thing.

Related to Explaining Water Flow: Inlet vs Outlet Pressure

1. What is inlet and outlet pressure?

Inlet pressure refers to the pressure of the water entering a system or device, while outlet pressure refers to the pressure of the water leaving the system or device.

2. How do inlet and outlet pressure affect water flow?

Inlet and outlet pressure play a significant role in determining the rate of water flow. Higher inlet pressure will result in faster water flow, while lower inlet pressure will result in slower water flow. Outlet pressure can also affect water flow, as it can create resistance and impact the overall pressure and flow rate.

3. What factors can affect inlet and outlet pressure?

Inlet and outlet pressure can be influenced by a variety of factors, including the size and design of the system or device, the elevation and location of the inlet and outlet, the amount of water being used, and any external forces acting on the system (such as gravity or external pressure).

4. Does water temperature affect inlet and outlet pressure?

Yes, water temperature can impact inlet and outlet pressure. As the temperature of water increases, the pressure also increases. This is because warm water has a lower density than cold water, and therefore requires more pressure to maintain the same flow rate.

5. How can inlet and outlet pressure be adjusted?

Inlet pressure can be adjusted by using a pressure regulator, which regulates the amount of pressure entering the system. Outlet pressure can be adjusted by using valves or other devices to control the resistance and flow rate of the water leaving the system.
