4 GATE previous year questions on One-dimensional compressible flow, nozzles (Fluid Mechanics, Mechanical Engineering) with answers and explanations, from every paper.

1. GATE 2022 ME (ME1) Q30 (1 mark, Multiple select) – The figure shows a purely convergent nozzle with a steady, inviscid compressible flow of an ideal gas with constant thermophysical properties…
2. GATE 2023 ME Q20 (1 mark, Multiple choice) – Consider an isentropic flow of air (ratio of specific heats = 1.4) through a duct as shown in the figure. The variations in the flow across the…
3. GATE 2024 ME Q40 (2 marks, Multiple select) – Steady, compressible flow of air takes place through an adiabatic converging-diverging nozzle, as shown in the figure. For a particular value of…
4. GATE 2026 ME Q25 (1 mark, Multiple choice) – An ideal gas passes isothermally through a long horizontal uniform cross-section pipe under steady flow. Consider that the pressure gradient in the…
