Unformatted text preview: (b) Compute the friction factor (c) Determine the viscosity of the liquid in centipoises Problem #3: A horizontal tube with diameter 4 in. and length 5.5 ft is packed with glass spheres of diameter 1/16 in., and the void fraction is 0.41. Carbon dioxide is to be pumped through the tube at 300K, at which temperature its viscosity is known to be 1.495 104 g/cms. Assuming ideal gas, (a) What will be the mass flow rate through the column when the inlet and outlet pressures are 25 atm and 3 atm, respectively? (b) Prove that Darcy’s law could be applied for gas flow in a porous medium. Problem #4: In a calculation using the Blasius formula for turbulent flow in pipes, The Reynolds number used was too low by 4%. Calculate the resulting error in the friction factor....
