Regarding the selection of pipeline flow velocity
Thread Content
I have a question: regarding the selection of pipeline flow velocity, are there any differences between metal pipes and non-metallic pipes? (For transporting liquids) When using glass fiber reinforced plastic pipes to transport liquids, how should the flow rate be determined? Additionally, if the liquid flows by gravity, glass fiber pipes are chosen – but how should the flow rate be determined?
The flow rate of the pipeline is determined based on the friction loss of the pipeline
The pipe flow rate has little to do with the material of the pipe; it mainly depends on what the working medium is and what the operating conditions are. Piping is generally determined based on operating pressure and medium properties. The flow velocity in gravity-fed pipes generally does not exceed 1 m/s.
The container is located about 5 meters above the ground, and the pressure inside the container is 10 kPa. Glass fiber pipes are used to transfer fluid from the container to the pump inlet, with the pump being placed on the ground. So, what diameter should the glass fiber pipes have?
It’s actually a matter of the pump’s net positive suction head. Based on your question, as long as it’s not at the bubble point, there aren’t many restrictions on the flow rate.
Based on the designed flow rate of the pump, determine the pipe diameter using the economic flow velocity!
Excuse me, what does the term \"bubble point state\" mean? When will this situation occur? Thank you.
The flow rate depends mainly on factors such as friction and power consumption; there is a recommended table for flow rates of different fluids~~
The selection of pipeline flow velocity is mainly related to the medium being transported.
The medium determines the flow velocity; the flow rate determines the pipe diameter
The resistance coefficients vary depending on the material; the pressure drop is different at the same flow rate. The flow rate is typically calculated using the volume flow rate and the pipe diameter, and it is then determined through the pressure drop
