The chief engineer of an airport is planning to rehabilitate runway pavements over the next several months. You ask him what impact this would have on delays and queues, but he does not know. Being a smart Georgia Tech student in CEE 3000, you realize immediately that this phenomenon could be modeled using a simple queue analysis. You figure out that airplanes arrive at the airport an average rate of 1 plane per 10 minutes, and that the arrival pattern could be assumed to follow the Poisson distribution. The airport control tower processes airplanes in their order of arrival. You also figure out that the service time could be assumed to follow the exponential distribution. If the service rate is 10 landings per hour, calculate the following parameters. Please use units of minutes for time-containing answers.
A) The average number of airplanes in the system (i.e. in the system and in the queue).
B) The average number of airplanes awaiting clearance to land.
C) The average time an airplane spends in the system.
D) The average time an airplane spends in the queue.
E) The probability that there is no airplane in the system.
Determine the smallest horizontal force P required to move the wedge to the right. The coefficient of static friction at all contacting surfaces is mu_s = 0.6. Set theta = 14^\circ and F = 490N . Neglect the weight of the wedge.
The coordinates for the benchmark are 1421334.93,783207.62 the first point in the survey for oleson village, is 113.66 feet from the benchmark and at a bearing of n5d27'23"w. this is other survey point 542.16 So how dose this work?

The cross-sectional geometry of bone varies along its length, although the cross-section can be approximated as hollow and circular, with an average outer diameter of 27 mm and inner diameter of 14 mm
A significant obstacle in the design of atomic weapons is theso-called delta phase instability (a type of mixed dislocation) inPu-239. This is the problem: We wish to construct a sphericalatomic bomb core out of pure delta phase (f.c.c.) Pu-239. A de..
A 0.9 efficient Francis turbine produces 200 MW with a speed of 150 rpm. The blade height is 1.0 m, and the inlet radius of the rotor is 7.0 m. The flow exits the turbine in a radial direction.
