#360615 — Shape of nose cone

What shape should a nose cone be to offer least resistance when moving 
along its own axis through a fluid medium?

I think this might help
<https://en.wikipedia.org/wiki/Nose_cone_design>

I will always be a genius as long as I can keep
my internet.

I must say I envy those brainy people who, wishing to know about nose 
cone design, look up "nose cone design" in Wikipedia.  It would never 
occur to a dullard such as me (or such as I?).

I thought it was quite an interesting link.  And I never would have 
thought of "nose cones", without the original post.  Bravo for the 
square root function!  Next time a student asks what the graph of the 
square root function is good for... : )

Me too.  This

   For aircraft and rockets, below Mach .8, the nose
   pressure drag is essentially zero for all shapes.

suprised me.

FWIW, the overall shape of an object has a great effect on the resistance.  The shape of the nosecone alone is not so important:
