Question 31
XE-BNAT2 marksNeeds review
Air flows over a smooth flat plate at a velocity of 4.39 m/s. The density of air is 1.031 kg/m³ and the kinematic viscosity is 1.34×10⁻⁵ m²/s. The plate length is 12.2 m in the direction of the flow. The boundary layer thickness (
) is given as
, where
is the distance from the leading edge and
is the Reynolds number. The boundary layer thickness (in meters, rounded off to the second decimal place) at 12.2 m from the leading edge will be ________Log in to check the answer
