How to calculate pipe diameter
Thread Content
Hello, I have a question: The flow rate is 100 m3 per second, the distance is 3000 meters, the height difference is 15 meters, and the medium is clean water, with flow occurring by gravity. What diameter is required?
Could you be more detailed and specific?:L:L:L:L:L:L:L:L:L:L:L:L
HG/T20570-95 \"Technical Specifications for the Design of Process System Engineering\" provides specific methods for calculating pipe diameters. Many standards also explain how to calculate the pipe diameter
100 M3/hr – is high precision required? A driving pressure of 0.15 MPa is too low; the pressure drop over 3000 meters would be very large~~ The pipes would have to be quite thick~~~~
Could you help me calculate it? Thank you! ! ! It doesn’t have to be very precise; anything over 100 will do. Water flows from the high-level reservoir to our production area by gravity
Based on estimates, for a 200-mm diameter seamless steel pipe over a length of 3,000 meters, with a flow rate of around 100, the pressure drop is approximately 0.09 MPa. For a 150-mm diameter pipe, the pressure drop is 0.35 MPa.
Due to the large flow rate and large pipe diameter, the Reynolds number is very high, estimated to be between 400,000 and 800,000
