A liquid of viscosity 0.09Ns/m2 is filled between two horizontal plates 10mm apart. If the upper plate is moving at 1m/s with respect to the lower plate which is stationary and the pressure difference between the ends of the flow channel 60m apart is 60kN/m2 . Determine

(i) The velocity distribution across a x- section of the flow channel (2 marks)

(ii) The discharge per unit width (4 marks)

(iii) The shear stress on the upper plate (2 marks)
