Background
Shikhar Singh is a Steam Consultant and IT Consultant at GyanTosh Fabricators Pvt. Ltd., where he works on steam system sizing, condensate recovery and the engineering content published on this site.
His degree is a BE in Information Technology rather than mechanical engineering. The steam side comes from two places, and both are worth naming rather than glossing: formal training — including the 16-hour "Steam Boilers, Steam & Condensate Systems" masterclass by WR Training Pro on Udemy, alongside further coursework on Udemy and Coursera — and hands-on exposure to the boilers, thermic fluid heaters and balance-of-plant equipment GyanTosh designs, fabricates, installs and commissions.
That combination is also why the calculators on this site exist. The steam engine behind them is a direct implementation of the IAPWS-IF97 standard — regions 1, 2 and 4 — and its unit tests assert agreement with the R7-97 verification tables to nine significant figures. Every figure quoted in these articles is recomputed from that engine rather than copied from a reference table, which means anyone holding the standard can check the arithmetic independently.
Where a number cannot be computed or sourced, these articles say so rather than estimating. Published capacities, efficiencies and project references are omitted unless GyanTosh can stand behind them.
