7-97 A coated sheet is being dried with hot air blowing in cross flow on the sheet surface. The surface temperature of the sheet is constant at
90\deg C
, while the air velocity and temperature are
0.3(m)/(s)
and
110\deg C
, respectively. The length of the sheet subjected to the blowing hot air is 1 m long. Determine the convection heat transfer coefficient and the heat flux added to the sheet surface. Treat the coated sheet as a vertical plate in cross flow. FIGURE P7-97
