Question

Engine oil at 100˚c and a velocity of 0.1 m/s flows over both surfaces of a 1-m-long flat plate maintained at 20˚c. the thermal boundary layer thicknesses (in m) at the trailing edge will be, given (engine oil (tf = 333 k): ρ = 864 kg/m3, ν = 86.1 × 10-6 m2/s, k = 0.140 w/m⋅k, pr = 1081):
