Looking for how to design a pipe manifold for petroleum products.I have 1x6" inlet and 10x6" outlets,Q=200m3/h,WP 3 bar.Which is the size of the main pipe??Are there any math calculations that give us the size?
Any help would be appreciated!!
Tog get the same fluid velocity, the square area of the manifold should have the same square area as the sum of the outlet pipe square areas (or inlet pipes). Divide by pi/4 on both sides of the equal sign you get:
D^2=d1^2+d2^2+d3^2+........+dn^2
where:
D is the Manifold OD
n is the branch number
dn is the branch pipe OD for branch n
If not all branches are in use simultaneously, then you can include only those that will be used (worst case) but be sure then. It may be costly to increase size at a later date.
