The internal diameter of a cast iron pipe is 300 mm and its thickness is 10 mm. If the pipe is supported at two points 8 m apart, what is the internal cross-sectional area of the pipe as per IS:1239 (Part 1)?
A) 0.0707 m2B) 0.0616 m2C) 0.0524 m2D) 0.0491 m2 As per IS 1239 (Part 1)-2004 for Pipes, the internal diameter is 300 mm or 0.3 m. The internal radius r = (Internal diameter/2) = 0.3/2 = 0.15 m The internal cross-sectional area A = πr2= π x (0.15)2= 0.0707 m2 Therefore, option A is the…
