Question

2. Water at a temperature of 80 °C and velocity of 1.2 m/s is flowing parallel to one side of a smooth flat plate. The plate is maintained at a constant temperature of 24 °C and is 0.8 m long and 0.5 m wide. Determine the following:

1. The heat flux at a distance x = 0.6m from the front edge of the plate, q” = ____________
2. The location of the maximum heat flux on the plate, x = _________
3. The total convective heat transfer from the water to the top surface of the plate,

                                                                                                                   q = __________

4. The convective heat transfer between the water and the plate from x = 0.6 m to x = 0.8m

                                                                                                                   q₂ = __________

for water: ρ = 987 kg/m³, µ = 528 x 10^-6 N·s/m², k = 645 x 10^-3 W/m·K, Pr = 3.42
