A sedimentologist working in a flow system. He takes particles having size -1 in phi Scale. If density of the particle and density of the fluid are, 2.65 gm/cm3 and 0.994 gm/ml respectively, then calculate the settling velocity is This is a blank in m/s, if the kinematic viscosity of the fluid is 0.004 cm-/s. calculate up to two decimal).
