You have been asked to calculate the density of an in-compressible Newtonian fluid in steady flow that is flowing continuously at 250°F along a 2500-ft pipe with a constant diameter of 4 in. and a volumetric flow rate of 2.5 ft³/s. The only fluid properties known are the kinematic viscosity, -7.14 × 10^-6 ft²/sec, and surface tension -0.0435 N/rn. Assuming that the flow is laminar and fully developed with a pressure drop of 256 lb_f/ft², calculate the density of this fluid if the no-slip boundary condition applies.
