A) 0.0707 m2
B) 0.0616 m2
C) 0.0524 m2
D) 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 correct answer.

Live loads or otherwise called super imposed loads are one important type of loading. To be considered by the engineer while designing a structure to ensure their safe design. Loads are the forces that may cause stresses, deformations, displacement and accelerations on a building. A structure or building component may be subject to various types of loads….

Beams and columns are the two important structural elements in constructions. Both the members are designed to transfer the load from the superstructure to the substructure. A beam is a horizontal or inclined member that runs between supports and transfers the loads to the columns, while a column is a vertical or inclined member that…

Masonry walls have been used in construction for centuries owing to their durability, fire-resistance, and aesthetic appeal. Masonry is the building of structures using individual units bonded together with mortar. Masonry walls are constructed by laying masonry units like bricks, concrete blocks, stones, etc. in horizontal layers along with mortar that binds them together. The…

Cantilever bridges span gaps using projecting arms from piers. No mid-supports allow clear navigation. Balances moments via counterweights. Long crossings in civil engineering require the use of cantilevers. Cantilever bridge designs elegantly stretch unsupported spans over waterways, roads, and valleys using balanced structural projections. The cantilevers’ graceful lines and sweeping shapes create iconic silhouettes recognizable…
