Physics · Fluid Mechanics
A liquid fills a horizontal capillary tube whose one end is dipped in a large pool of the liquid. The distance L travelled by the liquid meniscus inside the capillary in time t is given by L = kγaRbμc√t, where γ is the surface tension, R is the inner radius of the capillary, and μ is the dynamic viscosity of the liquid. If k is a dimensionless constant, what is the value of the exponent a?
