Buildings designed to partially heat rooms by passive solar heating rely on

Engineering

Paha777 [63]3 years ago
4 0

Explanation:Image result for buildings designed to partially heat rooms by passive solar heating rely on

A strictly passive design will use the three natural heat transfer modes exclusively—conduction, convection, and radiation. In some applications, however, fans, ducts, and blowers may help with the distribution of heat through the building

The outer surface of an steel alloy is to be hardened by increasing its carbon content. The carbon is to be supplied from an ext
hoa [83]

Answer:

Diffusion time needed for 610 degree celcius is 81.91 min

Explanation:

Given data:

Diffusion heat temperature =  826 +  273 = 1099 K

Diffusion time t_1 = 10 min

carbon concentration = 0.83%

D_O = 8.3\times 10^{-8}  m^2/s

Q_d = 78.5 kJ/kg

T_2 = 610+273 = 883 K

From Fick's formula we hvae

\frac{ C_x - C_o}{C_z -C_o} = 1 -erf(\frac{x}{2\sqrt{Dt}}

at specific concentration

\frac{ C_x - C_o}{C_z -C_o} = constant

then

(\frac{x}{2\sqrt{Dt}} = constant

(\frac{x^2}{{Dt}} = constant

Dt = constant

D_1 t_1 = D_2 t_2

t_2 = \frac{D_1 t_1}{D_2}

D_1 at T_1

D_1 = D_o exp(\frac{Q_d}{R t_1})

       = 8.3\times 10^{-8} exp(\frac{78.5\times 10^3}{8.314 \times 1099})

        = 1.54\times 10^{-11} m^2/s

similarly for D_2  for T_2

D_2 = 1.88\times 10^{-12} m^2/s

t_2 = \frac{D_1 t_1}{D_2}

      = \frac{1.54\times 10^{-11} \times 10}{1.88\times 10^{-11}}

  t_2    = 81.91 min

Diffusion time needed for 610 degree celcius is 81.91 min
