Forgot to mention the object would be under water.

If the surface was completely hydrophobic vs normal skin drag? If it changed would it be significant in an object with a 7:1 ratio? Thank you for your responses!

Gentlemen, all information is helpful, please let's keep this civil

Is there a particular reason for the tear drop shape? Would it not make more sense to have a missile shape but then taper the back, since the missile shape would have a lower frontal profile then the tear drop?

I am trying to make this object have the lowest drag coefficient as is possible. The object being a towfish. Is a soft point preferred over a solid point? Where the change occurs from the taper to the cylinder should that be rounded? on the back end where the fins are should I taper that end? Is...

Hi Does anyone know the drag coefficient of a missile. Would a missile have a lower drag coefficient then a torpedo? Thanks all

I very much appreciate your responses. The general problem is dragging a towfish through the water doesn't produce a straight angle. the line curves similar to that of the curved line when flying a kite. Initially the weight of the cylindrical object causes a direct angle from the source to...

Hi what I would like to know is a formula to know the depth attained by the sinker given the following variables Velocity 3 mph Line length 100 feet ( diameter being .009" ) Lead Sinker being 5 ounces in weight Mass ( line diameter x distance ( weight diameter .5" ) How do I calculate...

Hi, I have been trying to understand the formula for the drag of an object vs the depth of the object in Water. The variables are Velocity, Mass, Weight. Velocity being in Miles per Hour. Mass taken from the cross section of the weight as it moves through the water and the mass of the line used...
