In the UK a 300mm (12" = 305mm) steel pipe with wall thickness of 6.35mm will hold 53.24 litres per metre
20mm
V = 0.0002011 cubic meters or 201,100 cubic millimeters.
the wall thickness of sch 40 - 500mm dia pipe is 15mm or 16mm.
if pipe dia = 15 mmarea = pi x dia2/4 = pi x 152/4 = 176.7146 mm2pipe length = 1 metre = 1000 mmso pipe volume = 176.7146 mm2 x 1000 mm = 176714.6 mm31 cubic millimetre (mm3) = 0.001 millilitreso pipe volume = 176714.6 x 0.001 millilitre = 176.7146 millilitre
15mm drill bit and a drill.
It depends on the price (given by the supplier or shop) per metre of the pipe. One UK company on the internet gave a list price £11.10 per metre.
the wall thickness of sch 40 - 500mm dia pipe is 15mm or 16mm.
Considering the pressure is 17,000 BAR then its 4,521,906 Liter per nano second
Assuming it is 15mm. Buy 2 15mm couplers (compression, push fit, pre-soldered or end feed) and a length of 15mm copper pipe. Chop the copper pipe that needs replacing and connect as necessary. If you need any more help just ask.Ans 2 - If you're not familiar working with copper pipe, then it's much easier to get a length of PEX and two 'Sharkbite' or similar push fittings. This generally gives you more flexibilty and allows coverage over areas of the copper pipe that look faulty ( greenish spots) This will cost about the same but is an easier and more reliable repair for the amateur.
The volume of the pipe is 0.2078 gallon per foot of length.I have no idea how much water might be in it.
