Physics - Mechanical Properties of Fluids

Practise 110 TS EAMCET previous year questions on Mechanical Properties of Fluids, compiled from papers spanning 2001 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty TS EAMCET tests.

Mechanical Properties of Fluids has been asked in 24 of the 24 years of TS EAMCET papers analysed (2001–2024), with 110 questions in all. 35% of them were easy, 50% moderate and 15% tough. Most of its questions came from 2022, with 12 questions that year. In the last three years (2022–2024) it had 32 questions across 17 papers, about 1.9 per paper.

The chapter's 7 topics are not weighted equally: Surface tension (41 questions, 37%), Viscosity (19 questions, 17%), and Efflux of liquid (14 questions, 13%) have been asked the most. Surface tension has also led over the last five years, with 19 questions. Surface tension has produced the most tough questions (7).
