300mm is a very low head, you can't expect much flow through that pipe, but you can work it out from the mechanical energy balance equation.
schedule is the thickness of the pipe and class is pressure/temperature rating of a fitting or pipe
Wall thickness of 600 mm is 9.02 for pressure rating of PN 10 & 10.52for pressure rating of PN 16.
The 80 in 80 steel pipe indicates its wall thickness; the higher the number, the thicker the pipe. The pressure rating for a 5" schedule 80 steel pipe at 100 degrees Fahrenheit is 1857 psig.
Steel pipe varies in weight according to size and thickness (schedule).
In the UK a 300mm (12" = 305mm) steel pipe with wall thickness of 6.35mm will hold 53.24 litres per metre
300mm is a very low head, you can't expect much flow through that pipe, but you can work it out from the mechanical energy balance equation.
pipe schedule is an American definition to define pipe thickness and how much pressure can the pipe stand, schedules are 10,20,40,80.., pipe schedule is nearly close to the eurobian definition for pipe class.
t = PxDxA/2E where, t = thickness P = pressure D = pipe Diameter A = factor of safety E = tensile strength of pipe
Sizing of the line is an important study and calls for a techno-economic analysis. The various parameters that affect line size are:* Pressure: High pressure will reduce the pipe size, but will increase the pipe thickness* Size of the pipe: The bigger the pipe, the higher the cost* Thickness: Various factors affect the pipe thickness. E.g. Soil cover with the line having internal pressure/line in empty condition but having external soil pressure etc* Pipe material* Booster stations: How many booster stations will be there along the route? If the fluid pressure is low, the thickness decreases, but we need more booster stations and the reverse is the case if the fluid pressure is high* Pipe fabrication: Manufactured pipe versus roll-and-weld pipe* Buoyancy effect: Under-soil or underwater pipeline gets lifted up
