We extend the functional form of thermodynamic velocity of first sound in liquid helium near X transition, at different pressures, by using the heat capacity (as proposed by Chase[l], Pippard[2] and G. Ahlers[3]) to reach the hydrodynamic region ( I t [ = [ T-TΓ [ > 10 mK). For heat capacity we use
