A flow from an injector is leading to the formation of a spray of liquid drops. The drops formed in the spray have an average diameter d, which depends on the diameter of the pipe to which the injector is fitted D, the liquid velocity V, the acceleration of gravity g, and the liquid properties including density p, viscosity µ, and surface tension u. Using dimensional analysis, show that
