Compute the unit weight and kinematic viscosity, in foot-pound-second units, of dry air at 15 and an absolute pressure of 14.7 lb per sq.in

1.37 What is the specific weight of air at 70 psia and 70 °F?

Answer the attached question.

English (United States) Oil at 80°C (p = 56.8 lbm/ft³ and μ = 0.00278 lbm/ft*s) is flowing steadily in a 0.5-in-diameter, 120-ft-long-pipe. During the flow, the pressure at the pipe inlet and exit is measured to be 120 psi and 14 psi, respectively. Determine the volumetric flow rate of oil through the pipe assuming the pipe is inclined 20° downward. Accessibility: Investigate X TO
