That is not something you can easily calculate via a Formula. Why are you trying to calculate this?

that for my graduate project and i need that effect to calculate tha stabilty and how the slipstream effect in it

i think there will be lot of stability issues. I'm too trying to find the way to calculate the slipstream effect and find its path. Maybe using CFD or something. Maybe by keeping the horizontal tail at an height form the fuselage you can reduce the effect. Check it out.

thx for the re and i fiend out report for nasa and after working in it i think the effect will be increas in the dunimec pressuer and increas in the roll moment due to propwash as the thrust increas
