In an injection moulding process, at 170C, polyethylene behaves as a power law fluid with the shear stress

In an injection moulding process, at 170C, polyethylene behaves as a power law fluid with the shear stress (Pa) and shear strain rate (s) related by the following equation: T = 500 (y)-0.5 The flow of a power law fluid through a tube is given by: 2= [ (dP/dx) A flow rate of 5.9 m/s is required down a tube of length 10 cm, along which the pressure drop is limited to 0.8 MPa. Calculate the minimum diameter needed for the tube.
