Air at 20C flows over a 4-m-long and 3-m-wide surface of a plate whose temperature is 80C

Question:

Air at 20°C flows over a 4-m-long and 3-m-wide surface of a plate whose temperature is 80°C with a velocity of 5 m/s. The rate of heat transfer from the laminar flow region of the surface is
(a) 950 W

(b) 1037 W

(d) 2640 W

(e) 3075 W
(For air, use k = 0.02735 W/m.K, Pr = 0.7228, v = 1.798 × 10^-5 m²/s)
