A thin equilateral triangle plate with a = 95 cm (as shown below) is immersed parallel to a U = 11.9 m/s stream of air at 20 °C and 1atm.

Assuming Re = 10° and laminar flow, estimate the drag of this plate. Take the density and dynamic viscosity of air at 20 °C and 1atm, as pa =1.2 kg/m and u = 1.8 x 105 kg/(m s).U ) Drag force: il) Re:
