Textbook Question
Chapter 1, Problem 1.43P
Using spreadsheet software (such as Microsoft Excel), create a list of 1,000 numbers each randomly selected between 100 and 999. Divide each number by 10 to obtain a trailing digit; this will be Column 1. Each number in Column 1 will have three significant digits. In Column 2, have the spreadsheet round each number using the default ROUND function to two significant digits. In Column 3, have the spreadsheet round each number in Column 1 per ASTM E29 (e.g., (=IF(MOD(A1,1)= 0.5,MROUND(A1,2),ROUND(A1,0)). Compute the sum of each column and compare. Discuss the meaning of the operations and the results, and explain any differences due to rounding errors.

6.76 A wind turbine is operating in a 12 m/s wind that has a den-
sity of 1.2 kg/m³. The diameter of the turbine silhouette is 4 m.
The constant-pressure (atmospheric) streamline has a diameter
of 3 m upstream of the windmill and 4.5 m downstream. Assume
that the velocity distributions are uniform and the air is incom-
pressible. Determine the force on the wind turbine.
