A pipe system is shown schematically in the diagram. There is a T-junction at point B from which a pipe (coloured red in the figure) leads, ending at point D after a single right-angled bend. BC continues straight on from from point B to the end at point C. There are identical taps located at points B and C. What is the maximum length of BC for the mass flow through it to be just 95% of the mass flow rate through BD? Answer to the nearest 0.1m. For the system: • all pipes have a diameter of 22mm; • All pipes are smooth and the Blasius formula may be used. The mass flow rate through BD is 1kg/s. The length of pipe BD is 0.8m; the minor loss for straight flow through the T-junction is 0.9 and for flow through the branch is 2, the minor loss for a right-angled bend is 1.5, and the minor loss through a tap is 2; all the flows are inertially dominated; • the density of water is 1000kg/m3 and its viscosity is 10-3kg/ms; • The pressure of the central distribution system is fixed and unaffected by changes to the piping system. Thwe diagram is schematic and the lengths of BC and BD may be very different. m = 1kg/s B C Tap Tap D A pipe system is shown schematically in the diagram.
