(Laminar flow) Asphalt at 120°F, considered to be a Newtonian fluid with a viscosity 88,000 times that of water and a specific gravity of 1.60, flows through a pipe of diameter 2.00 in. If the pressure gradient is 1.64 psi/ft, determine the flowrate assuming the pipe is (a) horizontal (ft3/s) (b) vertical with flow up (ft3/s)

A circular, horizontal tube iwth r = 1 inch and L= 10 ft contains asphalt (? = 70 lbm/ft3 and µ = 67.1 lbm/ft s). A pressure gradient of 10 psi is applied and the asphalt begins to flow. Assuming that asphalt is a Newtonian fluid (which it sometimes is not) calculate the volumetric flow rate of the asphalt leaving the tube. Give your final answer in gpm. Answer should be 0.58 gpm

Consider a horizontal pipe in which a viscous fluid is moving at a laminar flow. The pressure drop across a 0.2-cm ID pipe was measured at 18,000 Pa/m. The fluid has a rho= 1110 kg/m3 and mu= 0.03 kg/m-s. Determine the equation that defines the velocity profile vz(r).Then, calculate the velocity at the center of the pipe (vzat r = 0 in m/s).
