Streamline

It is a path pursued by a particle of the fluid in steady motion.
Adding a tail to the spherical object in a manner that it fits the streamlines of the fluid, reduces the tendency to form eddies. Under such a situation, the moving object slips through the fluid with minimum disturbance.
An object which is shaped in a manner that the eddies are not formed when it moves at great speeds through the fluid is said to be streamlined.
Aircraft moving with high speed encounter high drag force. It is, therefore important to have mirror smooth surfaces and streamlined shape for a high speed aircraft.
The speed of an aircraft is given interms of Mach Number
Speeds below Mach 1.0 are called subsonic, while above Mach 1.0 are called supersonic. Very high speeds corresponding to Mach 5 are called hypersonic.
