1.	How can you detect whether the motion of a liquid is streamline or turbulent ?
Answer» Solution :Let a liquid flow through a NARROW PIPE of UNIFORM cross SECTION. A coloured solution is injected along the axis of the pipe at the point of entry.If this coloured solution flows like a thread along the axis of the pipe , then it is in streamline motion. The coloured solution spreads all over the liquid in the case of turbulent motion.
