    Electric Potential inside and outside a spherical Shell

    1. Find the electric potential inside and outside a uniformly charged sphere of radius R, and whose total charge is q. Use infinity as your reference point. Compute the gradient of V in each region and check that it yields the correct field. Sketch V(r). 2. I used the theorem that electric...

    Aerodynamic Heating: Equation for Rate of Heating?

    I do not think in my case that the nose cone will disperse the air around the rocket like it does in the F-22 design. Furthermore, I have a raytheon design guide on missile design and I am using as a reliable reference for this rocket. In this guide it states that "the highest heating rates on...

    Aerodynamic Heating: Equation for Rate of Heating?

    First off, I do not understand why you are saying that the fins will be in a subsonic airflow and how this affects it being cooler. And secondly, I would be inclined to think that the heating on the fins would be greater than the rest of the rocket because they are protruding from the rocket...

    Aerodynamic Heating: Equation for Rate of Heating?

    To be a little more clear I am trying to get a good empirically value for how hot the back fins of a rocket I am constructing will get. I am assuming that the equation I am looking for will most likely have to be in the form of a rate of change rather than an exact value so that I can account...

    Aerodynamic Heating: Equation for Rate of Heating?

    Is there an equation for the rate of heating on a surface at any time, and at any angle?

    Aerodynamic heating on rocket fins

    I am currently constructing a supersonic rocket and am trying to empirically calculate the heat transferred onto all different parts of the missile body to know what materials to buy. However, I do not know how to calculate the heat transferred onto the fins of the rocket as it travels (the fins...
