how can we reduce fluid friction without changing speed of the object and nature of the fluid
Answers
Answer: Air is very light and thin, yet it exerts frictional force on objects moving through it. When an object moves through the air ,it pushes the air out of the way and air pushes back on the object. This push of air on the moving object creates fiction which tends to slow down the moving object. Air exerts frictional force on cars, buses ,aeroplanes ,rockets and birds moving through it. Water exerts force of friction on object which move through them and opposite their motion. When an object moves through water, it pushes the water out of the way and the water pushes back on the object. This push of water on the moving object creates fiction which tends to slow down the moving object. Water exerts frictional force on objects like boats, speed boats ,ships ,submarines and fishes which Move through it.

Explanation:
Answer: By giving the object a streamline shape without changing the speed of the object we can reduce the fluid friction and since the speed of the object is unchanged so the nature of the fulid will remain same.
