30-minute practice mock for Chapter 3 Fluid Mechanics and Machines (AMeE03): 30 MCQs (18 conceptual, 12 numerical) covering fluid properties and statics (continuum, viscosity, surface tension, manometry, hydrostatic forces), fluid kinematics (flow types, Reynolds number, stream and potential functions, vorticity, circulation), flow equations (continuity, Euler, Bernoulli, flow measurement, momentum, dimensional analysis and similitude), laminar flow and boundary layers (pipe and plate flow, major and minor losses, separation), hydraulic turbines (Pelton, Francis, Kaplan, governing, cavitation, draft tube, specific speed) and pumps (centrifugal and reciprocating, priming, NPSH, performance curves, affinity laws). Take g = 9.81 m/s² and water density 1000 kg/m³ unless stated.
