Calculate the contraction linear expansion of 1500cm of steel pipe cooled through 70c°?

Answer 1

The linear contraction of 1500 cm of steel pipe cooled through 70°C can be calculated using the formula ΔL = L0 * α * (T2-T1), where L0 is the original length of the pipe, α is the coefficient of linear expansion for steel, and T2 and T1 are the final and initial temperatures respectively. In this case, the initial temperature is 20°C and the final temperature is 70°C. Thus, the linear contraction of the pipe is calculated as ΔL = 1500 * 12 * 10^-6 * (70 - 20) = 0.024 m.

Answer 2

The linear contraction of 1500 cm of steel pipe cooled through 70°C can be calculated using the formula ΔL = L0 * α * (T2-T1), where L0 is the original length of the pipe, α is the coefficient of linear expansion for steel, and T2 and T1 are the final and initial temperatures respectively. In this case, the initial temperature is 20°C and the final temperature is 70°C. Thus, the linear contraction of the pipe is calculated as ΔL = 1500 * 12 * 10^-6 * (70 - 20) = 0.024 m.
