I think Andy was correct. For non transparent bodies: emissivity+albedo=1

Hi, I am studying thermal radiation. Does anyone know what is a connection between emissivity and albedo. Regards, Mike

Yes, they intersect in 3 points, but the third point is not important for me. I am not sure if you can see the sketch, I am sure I attached it, but I cannot see it.

Huh... is it possible to make an approxiamtion? I would like to calculate the intersection between a sine function and a linear function. A sine function is of a form: y=A*sin(x). A linear function intersects sine function in two points. The first one (P1(pi,0)) is known, but we do not know...

Hi, I wolud like to solve the folowing equation: A*cos(B*t)+sin(B*t)*(C-t)-D=0 (t is unknown) It is urgent. Thanks in advance. Regards Mike

If you consider an air - water vapor mixture, total pressure of the mixture consists of water vapor pressure and air pressure. Does saturation pressure of water vapor change if the total pressure (air pressure) is changed. Regards, Mike

Hi, I think the derivation in the case of non uniform grid should be similar as in the case of the uniform grid. Write down your differential equation, I will try to help you.

What happens if you cool the mixture of water vapor and air to the temperature lower than 273 K? Since saturation pressure is higher than 0 some vapor should stay in the air. In the solid form?
