Fluid Statics Crossword Puzzle

QUESTIONS LIST:

• hydrostatic equation: the pressure gradient is equal to the specific weight of the fluid column.
• shear: fluid statics does not have _ stresses.
• absolute vacuum: space which does not contain any matter i.e. pressure=0 (i.e. absolute zero pressure)
• vacuum pressure: when the pressure at any location is below atmospheric pressure and is measured relative to the atmospheric pressure.
• gauge pressure: when the pressure at any location is above atmospheric pressure and is measured relative to the atmospheric pressure.
• negligible: in a manometer the diameter of the tube should be large enough so that surface tension and capillary effect are _ .
• barometer: atmospheric pressure is measured by a device called a _ .
• pressure: in fluid statics, for a vertical wall the point through which the resultant force acts is called the center of _ .
• vertical: for a curved surface holding a fluid the _ force is equal to the weight of the fluid supported by the wall.
• centroid: the horizontal (x direction) of the forces acting on a parabolic surface is also the position of the _ of the volume of water supported by the parabolic surface.
• buoyancy: the location of the buoyant force is: through a vertical line of action, directed upward, which acts through the centroid of the volume of fluid displaced. it is called center of _ .
• lactometer: a hydrometer to measure the purity of milk.
• stable: a floating body is _ if, when it is displaced, it returns to equilibrium.
• unstable: a floating body is _ if, when it is displaced, it moves to a new equilibrium.
• gravity: the location at which the body weight acts is called it center of _ .
• metacentre:if the _ , m, lies below the centre of gravity, g, then the body is unstable.
• archimedes: the buoyant force acting on a body of uniform density immersed in a fluid is equal to the weight of the fluid displaced by the body, and it acts upward through the centroid of the displaced volume. this is _ principle.
• free fall: a = -g
• isobars: lines of constant pressure.
