Hydrodynamics describes the low-energy long-wavelength limit in physical systems. The constitutive relations in hydrodynamics are usually specified in a derivative expansion. Beyond the zero order in derivative expansion, however, the hydro fields like velocity are not uniquely defined. Choosing the fluid velocity is referred to as the choice of frame in hydrodynamics. In this talk I will try to explain how different hydrodynamic frames are transformed to each other in a chiral fluid. The obtained transformations then make us be able to reproduce the well-known results on the transport coefficients, collective excitations and drag force in a chiral fluid from the computations in the framework of chiral kinetic theory.
