In summary, the pressure increase in the fluid in a syringe when a nurse applies a force of 43 N to the syringe's circular piston, with a radius of 1.1 cm, can be found by calculating the force multiplied by the area of the piston. However, the pressure is also defined as the force applied over a specific area, so the answer should be calculated by dividing the force by the area of the piston. This results in a pressure increase of 3918.18 Pa.

Homework Statement



Find the pressure increase in the fluid in a syringe when a nurse applies a force of 43 N to the syringe's circular piston, which has a radius of 1.1 cm.

Homework Equations

The Attempt at a Solution


So the answer should just be the force multiplied by the area of the plunger, no?
43N*pi*0.011m^2
0.016346 Pa

No. How is the pressure defined?

1. What is simple pressure?

Simple pressure refers to the force exerted by a fluid on the walls of its container or any object placed within the fluid.

2. How is simple pressure different from absolute pressure?

Simple pressure is the pressure at a specific point in a fluid, while absolute pressure takes into account the atmospheric pressure in addition to the pressure of the fluid.

3. What is the equation for calculating simple pressure?

The equation for calculating simple pressure is P = F/A, where P is pressure, F is the force exerted by the fluid, and A is the area over which the force is applied.

4. What are some common units for measuring simple pressure?

Some common units for measuring simple pressure include pascals (Pa), kilopascals (kPa), pounds per square inch (psi), and atmospheres (atm).

5. How does simple pressure affect objects submerged in a fluid?

Objects submerged in a fluid experience pressure from all directions, causing a net force on the object. This can result in buoyant forces and changes in the object's shape or volume.
