Answer : The rate of heat transfer from air to plate is 22 KW
Explanation :
It is given that,
Temperature of flat surface, [tex]T_1 = 30^0\ C[/tex]
Temperature of flat surface,[tex]T_2 = 80^0\ C[/tex]
Area of surface, [tex]A=8\ m^2[/tex]
Heat coefficient, [tex]H=55\ W/m^2K[/tex]
So, rate of heat transfer,
[tex]Q=HA(T_2-T_1)[/tex]
[tex]Q=55\times 8\times (80-30)[/tex]
[tex]Q=55\times 8\times 50[/tex]
[tex]Q=22000\ W[/tex]
[tex]Q=22\ KW[/tex]
Hence, the rate of heat transfer from air to plate is 22 KW
