X.2907L - FLOW OF LIQUIDS THROUGH NOZZLES We have carried out some experiments on the flow of liquids through cylindrically shaped nozzles of various bores, lengths and bore-length ratios, with a view to determining how the discharge under a given head varies with variation of these quantities. The nozzles experimented upon were according to the following table in which the unit for bore and length is 1/64 th.inch:- Nozzle Bore Length Length:bore ratio Average coeff: of discharge Observed.
