The fl ow of a liquid in a 2-in nominal diameter steel pipe produces a pressure drop due to friction of 78.86 Pa. The length of pipe is 40 m and the mean velocity is 3 m/s. If the density of the liquid is 1000 kg/m 3, then a. Determine the Reynolds number. b. Determine if the fl ow is laminar or turbulent. c. Compute viscosity of the liquid. d. Estimate the temperature, if the liquid is water. e. Compute the mass fl ow rate
