of any fuel carried by the airplane. The maximum lift coefficient, with flaps fully em ployed at touchdown, is 2.5.

A flat plate has a surface roughness of 0.1 mm, a width of 3 m, and a length of 2 m. Air with a velocity of 3 m/s flows over the plate. a. Calculate the drag exerted on the plate if the flow at the leading edge of the plate is laminar. b. Calculate the drag exerted on the plate if the flow at the leading edge of the plate is immediately tripped to turbulence due to the presence of an exposed bolt

A three-blade propeller of a diameter of 1.5 m has a rotational speed is 60 Hz, the activity factor AF is 200 and its static torque coefficient is 0.05. The propeller's integrated lift coefficient is 0.3.

An aircraft has a total mass of (1.18x10^2) kg and a wing area of (1.4000x10^1) m². It operated with an aerofoil section having C = 1.0 and Cp30.1. Assuming that the total drag of the wing represents the whole drag of the aircraft, find the power input required for to overcome gravity and take off. Assume density of air to be 1.2 kg/m3. Answer should be in Watts with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible.

#1. Consider a Boeing 747-700 in straight-and-level cruise flight on a standard day. The aircraft has a wing area of 525 m and is flying geometric altitude of he = 10,000 m. At a certain time during the flight, its mass is 3.5 x 105 kg and each of the four engines produces 50 kN of thrust. C was calculated as 0.4. a) Determine the cruise airspeed. b) Determine the total drag coefficient.

Nellie and Goldie are coasting on their bicycles down a 10° slope at 15 m/s through still air. The mass of Nellie and her bicycle is 60 kg. The mass of Goldie and her bicycle is 90 kg. The cross-sectional area of Nellie and her bicycle is 0.45, while the cross-sectional area of Goldie and her bicycle is 0.60. The drag coefficient for both cyclists is 0.70. Other than gravity and air resistance, the external forces acting on the two bicycle and rider systems are the same. Which cyclist is more affected by air resistance, and why?

The drag force acting on a 60 kg skydiver in the "spread" position shown can be approximated by Fo = 0.0436v², where Fo is in newtons and v is in m per second (from Scientific and Engineering Problem-Solving with the Computer, W.R. Bennett, Jr., Prentice Hall, New York, 1976). If the skydiver follows a vertical path, determine the terminal velocity.
