A liquid of density  kg m⁻³ is filled in a cylindrical tank of upper radius  m and lower radius  m. A capillary tube of length  is attached at the bottom of the tank as shown in the figure. The capillary has outer radius  m and inner radius . When pressure  is applied at the top of the tank, the volume flow rate of the liquid is  m³/s, and if the capillary tube is detached, the liquid comes out from the tank with a velocity  m/s. Determine the coefficient of viscosity of the liquid (in SI units). [Given  m² and  m]
