4. Experiment: Click Reset. Choose a new set of boat dimensions. Add cubes to the boat and record the volume of the displaced liquid. (If the boat sinks, try a larger set of dimensions.) Record your findings for three boats in the table (include units). Leave the last column blank. Leng Height (cm) Width Boat Volume of Mass of displaced liquid (g) (cm) th displaced liquid (mL) mass (cm) (g) 7cm 7cm 7cm 300(g) 300mL 8cm 8cm 8cm 500(g) 500mL 9cm 9cm 9cm 700(g) 700mL 5. Calculate: Density is equal to mass per unit volume. To calculate density, divide an object's mass by its volume. If the liquid's density is 1 gram per millilitre (the density of water), the mass in grams is equal to the volume in millilitres. Use this information to fill in the last column of your data

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.
