Extracted text: Q2) The size (d,) of droplets produced by a liquid spray nozzle is demonstrated to depend upon the nozzle diameter (D), jet velocity (v), liquid density (p), liquid viscosity (u), and the surface tension (6). Apply dimensional analysis (MLt system considering D, p, and v as repeating variables) to obtain the groups describing the jet system. Note: Surface tension is measured by N/m
