A plane wall has thickness of 5 cm, thermal conductivity of 2 W/mK and generates heat. The left face of the wall (x=0) has a surface temp. of 80C and has air at 20C flowing past it with a heat transfer coefficient of 50 W/m^2K. If the right face is insulated then the temperature distribution through the wall has a general format T(x)=A+B*x+C*x^2 (a) Draw a properly labeled diagram (including a representative temperature distribution), state all assumptions and calculate the...

Anatomy absorbs x-rays based on the density of the structure (subject thickness). Considering your understanding of how black, grey, clear and white tones (radiolucent and radiopaque) are created on an x-ray film, Why do some anatomical structures appear black, and others clear or white? Why do some structures allow more x-rays to pass through and energize the film crystals, while others do not?
