We derive several relations between CP violating rate differences {delta}(B{yields}PV)={gamma}(B{yields}PV)-{gamma}(B(bar sign){yields}P(bar sign)V(bar sign)) for charmless B{yields}PV decays in the standard model using SU(3) flavor symmetry. It is found that although the relations between branching ratios of {delta}S=0 and {delta}S=-1 processes are complicated, there are simple relations independent of hadronic models between some of the {delta}S=0 and {delta}S=-1 rate differences due to the unitarity property of the Kobayashi-Maskawa matrix, such as {delta}(B{yields}{pi}{sup +}{rho}{sup -})=-{delta}(B{yields}{pi}{sup +}K{sup *-}), {delta}(B{yields}{pi}{sup -}{rho}{sup +})=-{delta}(B{yields}K{sup -}{rho}{sup +}). SU(3) breaking effects are also estimated using the factorization approximation. These relations can be tested at B factories in the near future. (c) 2000 The American Physical Society.
