steposvetlana [31]

Answer:

The answer is "12682.267\ \ \frac{W}{m^2}"

Explanation:

Calculating the mass flow rate of fluid:

m= \rho AV

   = \rho \frac{\pi}{4} D^2\ V\\\\= 100 \times \frac{\pi}{4} \times (0.0127)^2\times 0.2\\\\=0.0253 \ \frac{kg}{s}\\\\

Calculating the amount of heat transfer.

q =m\timesC_p(T_{m,0}-T_{m,i})

  =0.0253 \times 4000 (75-25)\\\\=0.0253 \times 4000(50)\\\\=0.0253 \times 200,000 \\\\= 5060 \ W

Calculating the required value for heat flux:

q"=\frac{q}{A_s}

   =\frac{q}{\pi DL}\\\\= \frac{5060}{\pi \times 0.0127 \times 10}\\\\= 12682.267 \frac{W}{m^2}\\
