i need the solution with comsol

Consider a large plane wall of thickness L 5 0.4 m, ther- mal conductivity k 5 2.3 W/m·K, and surface area A 5 20 m 2 . The left side of the wall is maintained at a constant temperature of 95°C, while the right side loses heat by convection to the surrounding air at T ` 5 15°C with a heat transfer coefficient of h 5 18 W/m 2 ·K. Assuming steady one-dimensional heat transfer and taking the nodal spacing to be 10 cm, ( a ) obtain the finite difference formulation for all nodes, ( b ) determine the nodal temperatures by solving those equations, and ( c ) evaluate the rate of heat transfer through the wall

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...

Consider the vertical rear window of an automobile that has a thickness L= 9 mm and height H=0.5 m with heating wires that create uniform volumetric heating. The window interior is exposed to ambient air at 10°C and the window exterior to air at -10°C which moves in parallel flow over the surface with a velocity of 20 m/s. The surface temperature of the window exterior is 12°C. Find the volumetric heating rate necessary to keep the window interior at...

A loudspeaker sits in a large room (of length L) against a wall and faces towards the opposite wall. The speaker emits a resonant frequency of the room, thus setting up a standing wave. Assume that the wavelength is much smaller than the size of the room, so that the mode number n is high. Use vsnd for the speed of sound. a.)
