PRACTICE PROBLEMS.
1. The flow rate of chocolate syrup is 4 m^3/s and the cylindrical pipe in which the fluid flows has a diameter of 6 cm. Determine the Reynolds number for the fluid which has a density of 1268 kg/m^3 and a viscosity of 17 Pa*s. In addition, indicate if the flow regime is laminar or turbulent. 2. A fluid flows turbulently, at a rate of 3.5 m^3/s, through a cylindrical pipe. The pipe has a sectional area of 0.5 m^2 and the fluid has a viscosity of 1.2 N/(s*m^2) and a Reynolds number of 6283. What is the density of the fluid (in kg/m^3)? (Assume the fluid is incompressible and steady state flow. 3. A flow of whole milk at a Temperature of 293 K with a density of 1030 kg/m^3 and 2.12 cp viscosity, moves through a glass pipe with a mass velocity of 0,605 kg/s. The internal pipe diameter is 63,5 mm. a) Determine Reynolds Number. Is the flow turbulent? b) Determine also the flow rate in m^3 necessary for working for a Reynolds Number of 2100 and the velocity in m/s.
4. A flow of oil is being pumped inside a pipe of 10 mm of diameter with a Reynolds number of 2100. Density and viscosity of oil are given with values of 855 kg/m^3 and 2.1 x 10^-2 Pa*s correspondingly. a) What is the velocity inside the pipe? b) Keeping the Reynolds number of 2100 and the velocity obtained, transporting a new fluid with a density of 925 kg/m^3 and a viscosity of 1.5 x 10^-2 Pa*s. What should be the diameter to work with?
5. A gas of Chloroform with a density of 1,49 g/cm^3 is being transported through a 1 cm radius pipe with a rate of 2,5 m^3/s . If the environment works under a Temperature of 300 C. Using °
the charts find out the viscosity of Chloroform. What is the Reynolds number of the flow?
