1) Considere uma parede plana de espessura L = 20cm consti tuída de tijolos com condutividade térmica kt = 0,69 W/m. C A superfície esquerda é mantida à temperatura T0 = 25°C, enquanto a superfície direita permanece com temperatura TL = 10°C. Considerando um eixo x perpendicular às superfícies e com origem na superfície esquerda, determine, com o uso da equação da difusão de calor, a distribuição de temperatura T(x) e a densidade de fluxo de calor que atravessa a parede . 2) Considere uma placa plana de vidro de espessura L= 1 cm e condutividade térmica Kv=0,78 W/m. C . A superfície esquerda é mantida à temperatura T0 = 25°C, enquanto a superfície direita permanece com temperatura TL =10°C. Determine a densidade de fluxo de calor que atravessa a placa de vidro. 3) A Figura mostra um esquema de uma placa de mármore de espessura L = 2 cm e condutividade térmica Ki = 2,5 W/m. C . Asuperfície esquerda da placa é manti da à temperatura T(0) = 30°C, enquanto a superfície di

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
