This dataset represents the Indian Forest Service (Main) Examination 2018, Chemical Engineering Paper I. It includes metadata for the paper (paper code FSI-P-CHME, 200 marks, three-hour duration, Section A/Section B structure, and English-only answers) and a repaired OCR-based extract of Page 2 containing Q1 and its eight subparts (a–h), each carrying five marks. Subparts cover Fick's first law of diffusion, diffusion coefficient symmetry, ball mill operating speed, laminar vs turbulent flow, solvent selection in gas absorption, evaporator economy, centrifugal pump curves, momentum transfer equation with creeping/inviscid flow assumptions, and shell-and-tube heat exchanger design criteria. SEO-ready metadata is provided for improved discoverability.
