Objective : CFD Calculation in Matlab's PDE Toolbox
Goal : 3D flow pressure and velocity plot for the cycilnder pipe.
Flow : Laminar Flow.
Pro's of PDE Toolbox : Best suited for themal conduction and structural formation.
What I am looking for : Solving 3D Navier Strokes equation inside Matlab PDE Toolbox.
Geometry : Pipe (Figure is attached).
Mesh : Wall of Pipe alone, How to messure pressure and velocity inside the pipe?
I gave in the points fashion, to construct my problem statement in clearer manner, Can you please help me to find out pressure and velocity of air inside the pipe?

Yes, there is purpose for 3D flow calculations.
Going to introduce an object inside the pipe, looks for the velocity and pressure calculation on the surface of the object and object will be different shapes and so.
In the initial stage, I'm looking only on the hollow pipe alone.

If you are not restricted to using the PDE toolbox you could possibly use either the CFDTool or FEATool Multiphysics GUI toolboxes which allow you to quite easily set up and perform 3D fluid dynamics simulations and solve them with for example the OpenFOAM and SU2 Code CFD solvers.

You may also check out the QuickerSim CFD Toolbox for MATLAB. Plots in this soft are generated automatically, additionally, there are some tutorials (https://quickersim.com/category/tutorials-en/), for some cases you can calculate the average pressure in the pipe using inbuilt commands, it quickly gives you desired data.
The toolbox provides the user with efficient CFD solvers and auxiliary (e.g. mesh-manipulation, preprocessing, and postprocessing) functions inside of MATLAB.
You can check out the free code or ask for a trial full verion here.
