Practice Engineering — Uganda Fluid Mechanics in the app →An engineer reports a pressure in SI units. Those units are named after a French mathematician. They are:Pressure is defined for every state of matter, but it matters most when discussing:The pressure a column of fluid exerts equals the weight of the fluid divided by the:A tyre gauge reads pressure relative to the surrounding air. Such a reading is called:Meteorologists often quote atmospheric pressure in a convenient unit. That unit is the:Rather than quoting density in units, engineers often compare materials using a dimensionless quantity. That qA block of wood and a block of brass of equal mass go into water. The brass sinks because of its greater:Pressure on a submerged object is larger underneath than on top, because pressure grows with:That net upward push on a submerged object is called the:If that upward force is smaller than the object's weight, the object will:A submerged object seems lighter than it does in air. That apparent weight loss equals the weight of the fluidMany worked examples assume a fluid with negligible viscosity. Such a fluid is called:The volume of fluid passing a location in a given time is the:For an incompressible fluid, the same amount must pass every point of a tube in a given time. That relation isWater leaves a narrow hose nozzle much faster than it travelled in the hose. That speed-up follows from:Applying conservation of energy to frictionless laminar flow links pressure with flow speed. That relation is:A measure of the internal friction inside a fluid is its:Smooth, parallel streamlines in a pipe indicate a flow that is:Irregular streamlines that change over time indicate a flow that is:A dimensionless indicator tells an engineer whether flow will be laminar or turbulent. It is the:Building that indicator for a tube requires the fluid density, its viscosity, the tube radius and the fluid's:A pressure gauge built from a U-shaped tube of mercury is called a:
