(a) There is a non-Newtonian fluid traveling in a transfer piping in a mass flowrate of 45,000kg/hr. Given that the density of this fluid is 1750kg/m3, calculate the maximum velocity of this fluid if the diameter of the transfer piping is 30mm. Let's K=700 mPa.sn and n=1. [10 marks] (b) If a fluid is a Newtonian fluid, describe the variables used in the equation of Reynolds number calculation. [10 marks]
