Therefore, the flow velocity distribution in the width direction was better than that in Example A, and the film distribution was uniform. In Example C, since the drainage port is provided at the bottom of the tank and the drainage amount can be adjusted, the flow velocity distribution in the width direction is improved more than in Example B, and the film distribution in the width direction is made uniform. did.
