    Find the view factor of a tillted cylinder-shaped poolfire?

    The problem is about how much radiation is received by the person. It is assumed that the amount of heat received by the person only comes from the area that is visible to that person. It is also assumed that the person is not able to see the top part of the cylinder. I have the area visible to...

    High School Given a cylinder of vertical height, H and radius R. h = H/R

    1.)Given a cylinder of vertical height, H and radius R. h = H/R So what does this equation means? what is h? 2.)Given L is the length from the cylinder base to an element at ground level, s = L/R. So what does s stand for?

    Find the view factor of a tillted cylinder-shaped poolfire?

    ok so phi1 and phi 2 give the angles of the two lines from the target to the cylinder which are tangent to the cylinder.they are the angles of the edges of the visible part of the cylinder. phi1=3.3386 phi2=6.1454 zmin=0 zmax=19.2 diameter of cylinder,D=10m visible area=integration...

    Find the view factor of a tillted cylinder-shaped poolfire?

    I have the max and min angles that determine the area that the person can view. I also have the max length of the cylinder and the area of the cylinder. How can I use the formula using all the variable that i have? Do you know how to find the area of the visible part using Numerical integration?

    Find the view factor of a tillted cylinder-shaped poolfire?

    the shape of the absorbing area is a very small rectangle. the emmiting area is a sheared tilted cylinder.but it retains its circular shape.say the absorbing area is a person, the view factor needed does not include the top and bottom part of the cylinder.only part of the side of the cylinder...
