the velocity v for the stream-line flow of liquid l of a small uniform tube depends on the radius r of the tube, the density ¶ of the liquid and the coefficient of viscosity μ if the liquid. using the method of DIMENSION ANALYSIS obtain an expression for the velocity
GIVEN that v = r²¶/4μl
where ¶/l =pressure gradient
obtain an expression for the dimensionless constant in your expression of the above.
2. show whether or not the expression
s = utsin∅ - ½gt² is dimensionless?
