Question:

Repeat Problem 4.29, parts (d), (e), (g), and (h) for x = 4.0 m and U?? = 80 m/s, (a) taking the laminar boundary layer into account and (b) assuming that the turbulent boundary layer starts at the leading edge.From Problem 4.29: Hydrogen at 15?C and at a pressure of 1 atm is flowing along a flat plate at a velocity of 3 m/s. If the plate is 0.3 m wide and at 71?C, calculate the following quantities: (Take properties at 43?C.)(d) Rate of heat transfer, in W.(e) Drag force (D) in N.(g) Average convective heat transfer coefficient (hc) in W/(m2 ?C).(h) Rate of heat transfer (q) in Watts.GIVENHydrogen flowing over a flat plateHydrogen temperature (T??) = 15?CHydrogen pressure = 1 atmVelocity (U??) = 80 m/sPlate temperature (T w) = 71?CWidth of plate = 0.3 mASSUMPTIONSSteady stateConstant fluidproperties
