What is the formula for pressure?
Remember, P stands for pressure.
What happens to pressure as we go deeper in a fluid?
Think about what is above you when underwater.
What is the formula for pressure?
Think of how we measure force and area.
True or False: Pressure increases with depth in a fluid.
Consider what happens when you dive in water.
If you have a hydraulic system where a small force of 10 N is applied through a 2 m² area, what pressure is exerted? If this pressure is transmitted to a piston with an area of 4 m², what force will it exert?
Calculate pressure first, then use it to find the force.
A diver descends to a depth of 30 meters in water. Calculate the increase in pressure experienced by the diver compared to the surface pressure (approx. 101.3 kPa). Assume water density is 1000 kg/m³.
Remember the pressure increase formula involving density and depth.
