The local atmospheric pressure in denver, colorado (elevation 1610 m) is 83.4 kpa. air at this pressure and at 25°c flows with a velocity of 13 m/s over a 2.5-m × 5-m flat plate. the dynamic viscosity is independent of pressure, and for air at 25°c, it is μ = 1.849×10-5 kg/m⋅s. the air density at 25°c = 298 k and 83.4 kpa is 0.9751 kg/m3. calculate the drag force acting on the top surface of the plate if the air flows parallel to the 5-m-long side of the plate. the drag force acting on the top surface of the plate if the air flows parallel to the 5-m-long side is n.
