A hоrizоntаl pipe hаs аn inner diameter оf 3.0 mm and carries glycerin. a. If the average speed of the glycerin at 20°C is 0.47 mm/s and the viscosity is 1.50 Pa·s, what pressure gradient is required? (2 points) b. If the glycerin is heated and its viscosity decreases to 0.25 Pa·s, what is the new average speed in mm/s using the same pressure gradient from part a? (3 points) c. Using your answer from part b, calculate the Reynolds number for the heated glycerin. Use a density of 1260 kg/m³. Based on your result, determine whether the flow is laminar or turbulent. (2 points)
