Heat Transfer anyhing helps, thanks

2) A smooth flat surface is 20m by 20m square, made of stainless steel having a thermal conductivity of 50(W/m. k) and has a thickness of 0.3m as shown below. Very hot air at an average bulk temperature of 232.2C and 1atm abs flows parallel to the bottom part of the surface at a velocity of 20m/s. The bottom surface temperature of this surface is approximately uniform at 200"C. Above this surface, water is boiling under pressure at 135C. (a) Calculate the heat transfer coefficient for the air stream at the bottom of this plate (15 Points). hBottom (b) Using simplified equations, please predict the boiling heat-transfer coefficient for water under pressure boiling at 135C at the top of the plate (35 Points). h top
