b$)$ Calculate the heat lost by the plate $(20$ points$).$

$W_{4_x}=\frac{h_{x}x}{x}$

$h=\frac{N_{4xk}}{x}h=\frac{?}{b}$

$ar(N_4)=\frac{\mathrm{.}664(213675\mathrm{.}21{)}^{\frac{1}{2}}(\mathrm{.}7542{)}^{\frac{1}{3}}(\mathrm{.}02822)}{{20110}^{-2}}$

${}_x=\frac{h_{x}x}{K}=\mathrm{.}332R_{ex}^{\frac{1}{2}}{A}^{\frac{\text{'}}{3}}$

$\frac{\mathrm{.}332(213675\mathrm{.}21{)}^{\frac{1}{2}}(\mathrm{.}7042{)}^{\frac{1}{3}}(\mathrm{.}02822)}{{20110}^{-2}}$

$S^{-0}=\mathrm{.}0385$

PROBLEM #$1(35$ points$)$

Air at $1$ atm and $T_{}=300K$ flows across a $20$ cm by $20$ cm plate at a freestream velocity $U_{}=20\frac{m}{s}.$ The plate is maintained at a constant temperature of $T_s=350K.$ The critical Reynolds number is $5{10}^5.$

Use the following air properties for the calculation.
