In many pipe systems we will have a network of pipes connected in many different ways, this means that we may have sections of pipe connected in series and in parallel arrangements. The video shows how we can deal with these systems and define an overall fluid resistance:
The interactive calculator below shows the split in flow in two parallel pipes as in the figure below.
D0 = 0.2 m, h0 = 0 m, P2 = 1 atm.
Inlet Pressure: P0 = 1.146 atm
Manifold Pressure: P1 = 1.132 atm
Pipe 1: Q1 = 57.656 m3 hr-1
Pipe 2: Q2 = 122.344 m3 hr-1
