Chapter 17, Problem 22RQ
An Excel file named DartTosses.xlsx has one worksheet named Darts containing the horizontal and vertical distance from the bull’s-eye of a dart board from 20 different tosses of a dart. A portion of the data is shown below. Write the MATLAB code necessary to determine the darts that were the closest and the farthest from the bull’s-eye. The program should tell the user in the Command Window, using formatted output, the darts that are closest and farthest from the bull’s-eye.
| Dart | X | Y |
| Dart 1 | 4.04 | 0.55 |
| Dart 2 | 2.63 | 0.35 |
| Dart 3 | 1.10 | 2.97 |

You are working as an engineer in a bearing systems design company. The flow of
lubricant inside a hydrodynamic bearing (p = 0.001 kg m-1 s-1) can be approximated
as a parallel, steady, two-dimensional, incompressible flow between two parallel plates.
The top plate, representing the moving part of the bearing, travels at a constant speed,
U, while the bottom plate remains stationary (Figure Q1). The plates are separated by
a distance of 2h = 1 cm and are W = 20 cm wide. Their length is L = 10 cm. By
applying the above approximations to the Navier-Stokes equations and assuming that
end effects can be neglected, the horizontal velocity profile can be shown to be

Question 2
You are an engineer working in the propulsion team for a supersonic civil transport
aircraft driven by a turbojet engine, where you have oversight of the design for the
engine intake and the exhaust nozzle, indicated in Figure Q2a. The turbojet engine can
operate when provided with air flow in the Mach number range, 0.60 to 0.80. You are
asked to analyse a condition where the aircraft is flying at 472 m/s at an altitude of
14,000 m. For all parts of the question, you can assume that the flow path of air through
the engine has a circular cross section.
