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.

- Problem 3: Insulation To=1 Toowwww Steam Tx2 T₂ T3 www www R₁ R₁ R₂ www.T R₂ Steam at T1 = 320 °C flows in a cast iron pipe (k= 80 W/m. °C) whose inner and outer diameters are 5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation. The determination is based on a unit length of the pipe (L = 1 m). Assumptions 1. Heat transfer is one-dimensional since there is no indication of any change with time. 2. Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no variation in the axial direction. 3. Thermal conductivities are constant. 4. The thermal contact resistant at the interface is…arrow_forwardsample calculations 目 File Edit View Insert Format Data To 100% $ % .0 .00 12: fx | A 1 Variable Value Units diameter height m 4 volume m^3 3 The image above shows a section of a Google sheet.
