Afreezer compartment is covered with a 3-mm-thick layer of frost at the time it malfunctions. if the compartment is in ambient air at 20°c and a coefficient of latex: h=\: 2\: \frac{w}{m^2.k}h = 2 w m 2 . k characterized heat transfer by natural convection from the exposed surface of the layer, estimate the time required (in seconds) to completely melt the frost. the frost may be assumed to have a mass density of 700 latex: \frac{kg}{m^3}k g m 3 and a latent heat of fusion of 334 kj/kg.

3h12min

Explanation:

We need to apply our thermodynamics concepts to find the required time in which the ice will melt at a given temperature.

In our data we have defined that,

Performing an energy balance you have to:

Internal energy is given by,

Integrating,

Replacing the values,

Note: It was assumed that fros is isothermal and the radiation exchange is also negligible.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
