Fluid Mechanics Multiple Choice Questions on Boundary Layer Flow & Forces on Sub-merged Bodies

Temperature Pressure Viscosity Surface tension Atmospheric boundary layer Lithosphere Troposphere Hydrosphere Momentum boundary layer Atmospheric boundary layer Oscillatory boundary layer Thermal boundary layer Fluid Heat Momentum Pressure Smooth flow Rough flow Uniform flow Random flow Non-uniform with swirls Uniform Less stable Smooth Due to random motion Collision of molecules Due to eddies Due to non-uniform cross section Reynold’s number Mach number Froude number Knudsen number Surface Fluid body Adverse pressure gradient Inter-molecular spaces Vortices Vertices Volume Velocity Dead Weight Gauge Vacuum Gauge Turbulator Ionization Gauge True False Increases Decreases Remains Same Independent Resistance= 0 Drag force= 0 Temperature = 0 Pressure gradient= 0
