When a liquid moves steadily under come pressure through a horizontal tube, it moves in the form of cylindrical layers coaxial to the exds of the tube. The velocity of different layers is different. The velocity of the layer is maximum along the axis of the tube and it decreases as one moves towards the walls of the tube. According to Poiseuille, the rate of flow of liquid through a horizontal capillary tube varies as the relation V alpha (pr^(4))/(eta l) where l and rare the length and radius of the tube and p is the pressure different between the ends of the tube and is the constant of proportionality. Which of the following is correct:

1.	When a liquid moves steadily under come pressure through a horizontal tube, it moves in the form of cylindrical layers coaxial to the exds of the tube. The velocity of different layers is different. The velocity of the layer is maximum along the axis of the tube and it decreases as one moves towards the walls of the tube. According to Poiseuille, the rate of flow of liquid through a horizontal capillary tube varies as the relation V alpha (pr^(4))/(eta l) where l and rare the length and radius of the tube and p is the pressure different between the ends of the tube and is the constant of proportionality. Which of the following is correct:
Answer» The unit of COEFFICIENT of viscosity is Pa-s. coefficient of viscosity is a vector quantity. The DIMENSIONAL formula of coefficient of viscosity is `ML^(-2)T^(-1)`. WATER is more VISCOUS than blood Answer :A
