Luigi is attempting to fix some Mushroom Kingdom plumbing. At one point in the plumbing, a horizontal pipe is carrying an incompressible frictionless fluid of density 1.31×10³ kg/m³. The pipe widens from d1 = 2.59 cm at left to d2 = 6.61 cm at right, as shown below. %3D %3D d1 d2 If the fluid enters the narrower left end of the pipe at a speed of 2.33 m/s, by how much must the pressure drop or rise (in Pa) at the wider right end of the pipe? Be sure to include the appropriate sign!

Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
