Hi all,
I am trying to find out what pressure drop I get when I pump a fluid through annulus of one pipe that is placed (concentrically) inside another pipe.
Both of the pipes have a length of 20 ft, difference in radius equals 0,225 in and I pump a fluid against gravity.
When I run the first simulation with a slurry, with a density of 1,60 sg and pumping pressure of 1.000 psi I got reasonable results of around 500 psi pressure drop across the pipe.
However, when I tried to run a simulation with the same boundary conditions, with incompressible water with density of 1,0 sg I got an extreme pressure drop of around 950 psi.
Therefore I got 2 questions:
- What is the reason that I get larger pressure drop with 1,0 sg water than with 1,6 sg slurry?
- Why the solver shows that I was pumping with a pressure of 1.006 psi if my inlet pressure opening was set to 1.000 psi (total pressure)?
Appreciate all the help!
