Use the printing indicator formula, 1 Re We/2 = pry 10 (1) Calculate the minimum nozzle diameter which could be used for printing the materials with the following information. (2) Also calculate the length of the entry region le using formula provided. 0.06pvd = le = 0.06dRe (a) = 10cP, p = 1000Kg/m3, v = 1 m/s, y = 0.072 N/M, surface tension is 0.072 N/m, (b) u = 40cP, p = 1000Kg/m3, v = 8 m/s, y = 0.025 N/M, surface tension is 0.05 N/m.
