Do not understand SimpleFOAM algorithm in OpenFOAM
 
(1)Guess the pressure field p*
Solve the momentum equations to obtain u*,v*,w*
Solve the p' equation (continuity)
Correct pressure field p =p*+p'
Calculate the velocity corrections
u', v', w'
Correct velocity field
u =u*+u',
v =v*+v'
w =w*+w'
Treat the corrected pressure pas a new guess p* and go to

I do not know how we can find
p' from continuity?

Mr. Peric is your friend. He wrote full book explaining exactly what you asked.
