What is the viscosity of normal saline solution?
Normal saline is an aqueous solution of NaCl with a concentration of 0.9 percent (weight/volume). Therefore, there would be little discernible difference between the saline solution and pure water. Therefore, the viscosity of normal saline would be indistinguishable from the viscosity of water. More on the viscosity of water can be found here: http://en.wikipedia.
