      For hydrodynamic equations.computer simulations are performed to compare explicit and implicit difference scheme timesteps suitable to maintain their stability in the case of implicit difference equations solved by simple iterations. A conclusion is made that for an implicit differnce scheme the acceptable timestep is equal to a half of that for explicit one.
