Chapter 12, Problem 1RQ

Define accuracy or precision in terms of a process capability study.

Expert Solution & Answer
Check Mark
To determine

The accuracy or precision in terms of process capability study.

Explanation of Solution

The process capability study is the determination of the process inconsistency of a given feature. It is the ability to make parts in the specified limits.

The accuracy is the nearness of the calculated value to the given value. It can also be defined as the number of times the process is capable of giving the accurate results. Precision and accuracy are different precision is the closeness of the two values that have been calculated by the process. In the measurement of precision and accuracy, process capability is helpful. Process capability study gives the quantity of the precision and accuracy.

Problem 3: Insulation To=1 Toowwww Steam Tx2 T₂ T3 www www R₁ R₁ R₂ www.T R₂ Steam at Tx1 = 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…
