Acetic acid flows in a laminar regime at 20C in a circular tube. The length and inner diameter of the tube are 20 and 0.009 m, respectively. The viscosity of acetic acid is 0.00122 kg/(m.sec) and the pressure drop across the tube is given as AP = 450 Pa. a. Find the average velocity and the maximum velocity and plot the velocity distribution in the tube. b. How do the average velocities and maximum velocities change in the same tube when the pressure is halved and doubled? Show the graphical results of the velocity distribution on the same graph as given in part (a) and make a physical sense of the result.
