    Made a rather hurried reply to Chris’s query yesterday. Should also have said that if each petticoat has significant contraction, then you will need more pressure energy to drive the consequent increase in velocity energy – which is also not a good thing for the stage preceeding. Any interchange of velocity / pressure energy is lossy (pressure to velocity slightly so), hence leave the petticoats parallel.
