The pressure drop latex: \bigtriangleup p△ p, along a straight pipe of diameter d has been experimentally studied, and it is observed that for laminar flow for a given fluid and pipe, the pressure drop varies directly with the distance, l, between taps. assume that latex: \bigtriangleup p△ p is a function of d and l, the velocity, v, and the fluid viscosity. use dimensional analysis to deduce how the pressure drop varies with the pipe diameter. (must be solved using full method of repeating variables)
