The viscosity of water can be determined by studying the Poiseuille's ow in a capillary tube connected to cylindrical container as shown in the adjacent gure. The density and viscosity of water are given by 1.00 gcc" and 1.00 InN sm'g. The radius and length of the capillary is 1.00 mm and 20 cm. If Radius of the vessel is 15.0 cm, then the time taken for height of water to reduce to half the initial is a) 15.02 minute b) 1.502 hour c) 22.03 minute d) 42. 43 minute
