Terminal velocity of a flat plate falling aligned in air.Consider the fortuitous situation that a flat, steel plate 5 mm in thickness, 1 m in length and 0.5 m in width is falling through the atmosphere with its long side (1m) aligned with the direction of gravity. The density of the steel is 7800 kg/m3. The properties of the atmosphere are ρ=1.2 kg/m3; k=0.026 W/m K; υ=15 x 10-6 m2/s. Which of the following best represents the terminal velocity of the plate in mph?
