A blood solution is tested in a cylindrical Coutte viscosimeter. The apparatus is 0.100 m high. The inner, rotating cylinder has an outer diameter of 40.0 mm and the outer (fixed) cylinder has an inner diameter of 40.4 mm. The rotation speed is 6.1 rpm.

(a) Calculate the shear stress on the outer cylinder wall.

(b) What is the shear stress in the fluid at 0.2 mm from the walls?

(c) Sketch the velocity profile between the cylinders.

(d) Calculate the torque on the inner cylinder.

(e) Calculate the power required to drive the viscometer.

The blood density is 1051 kg/m3 and its viscosity is 4.1 E-3 Pa.s.
