Q. The boundary layer thickness at the location of a sensor on a flat plate in an incompressible, laminar flow of air is required to be restricted to 1 mm for an effective measurement. If the flow velocity is 20 m/s with 1 bar pressure, 300 K temperature, and 1.789×10˗5 kg/(m-s) viscosity, the maximum distance (in mm) of the sensor location from the leading edge is
