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.
