Glycerin at 40 degree C with a ρ = 1252 kg/m^3 and μ= 0.27 kg/m *s is flowing through a 2cm diameter, 25m long pipe that discharges into the atmospher at 100 kPa. The flow rate through the pipe is 0.048L/s.
A) Determine the absolute pressure 25m before the pipe exit.
B) At what angle θ must the pipe be inclined downward from the horizontal for the pressure in the enitre pipe to be atmospheric pressure and the flow rate to be maintained the same?
