Straight Pipe with imported velocity profile. Pressure gradient?

Hello,
I have simulated a straight pipeline (2d axissymetric, k-w sst with mesh y+ = 1.05) to obtain a fully developed velocity profile . After importing profile to the inlet of the pipe, static pressure gradient can be observed at the inlet. and on XY plot (red) . Why fluent assumes constance static pressure profile at outlet instead of consant value of Total pressure at outlet? Static pressure in pipe should be an inversed SQRT function of velocity (Bernoulli). Is it possible to set Constant total pressure at outlet to avoid pressure gradients at inlet?
