Pressure Calculation in pipe

In summary, the conversation involves discussing the specifications of a pipe, including its outer and inner diameter, length, normal and maximum inlet pressure and temperature, and mass flow rate. The question is what the outlet pressure and temperature are and what formula to use to solve the problem. An assumption of a roughness factor for the piping is suggested, along with calculating the Reynolds number and friction factor for turbulent flow. More information is needed to solve the problem accurately.

Outer dia=25mm,Inner Dia=24mm,Length=84,Normal innlet pressure=6 bar,Normal inlet temp=150°C,Max innlet pressure=11.5 bar,Max innlet temp=230°C ,Mass flow rate=4 kg/min,
what is the Outlet pressure&Temp?.Which formula I have to Use.Pls Help me

Are you given any equations, the viscosity, or the piping material?

To solve this I would assume a roughness factor for the piping (e=0.00015 ft is good) and calculate the reynolds number, then the fraction factor, then head loss, and then finally a pressure drop.

Unless the problem specifically tells you to assume ideal conditions and zero friction, you have to assume it is turbulent flow and use a the friction factor - otherwise the scenario is bogus!

Please let me know if you have any more info and we will solve this.
 

1. What is pressure calculation in a pipe?

Pressure calculation in a pipe refers to determining the amount of force per unit area exerted on the walls of a pipe by the fluid flowing through it. This calculation is important in designing and analyzing pipelines and other fluid systems.

2. How is pressure calculated in a pipe?

The pressure in a pipe can be calculated using the equation P = ρgh, where P is the pressure, ρ is the fluid density, g is the acceleration due to gravity, and h is the height of the fluid column. Alternatively, the Bernoulli's equation can also be used to calculate pressure in a pipe.

3. What factors affect pressure in a pipe?

The pressure in a pipe is affected by several factors, including the flow rate, fluid density, pipe diameter, pipe length, and the type of fluid being transported. Changes in any of these factors can result in changes in the pressure within the pipe.

4. Why is pressure calculation important in pipe systems?

Pressure calculation is important in pipe systems because it helps ensure the safe and efficient operation of the system. By accurately calculating pressure, engineers can determine the appropriate pipe size, fluid velocity, and other design considerations to prevent potential issues such as pipe bursts or leaks.

5. Are there any limitations to pressure calculation in pipes?

While pressure calculation is an important aspect of pipe system design, there are some limitations to consider. These include factors such as changes in fluid viscosity, temperature, and the presence of impurities, which can affect the accuracy of pressure calculations. It is important to account for these limitations in order to ensure the reliability of the system.
