Answer published by the source. Consult the official source to check your work against its answer.
question
On a pipe, heat transfer is accomplished through a straight fin extending into an air stream. The fin may be idealized as a flat square plate with a 5.1 cm side. The flow is measured at 12.2m/s, and is at a temperature and pressure of 15.6°C and 1atmabs., respectively. If the plate surface temperature is 82.2°C, calculate the heat transfer coefficient assuming (a) laminar flow, and (b) a rough leading edge, making the adjacent boundary layer completely turbulent.

options
- 60.67 W/m -°K for laminar flow, 77.18 W/m^2-°K for turbulent flow
- 70.67 W/m -°K for laminar flow, 65.18 W/m^2-°K for turbulent flow
- 50.67 W/m -°K for laminar flow, 85.18 W/m^2-°K for turbulent flow
- 45.67 W/m -°K for laminar flow, 90.18 W/m^2-°K for turbulent flow
