Question

Example: How much pressure is created when you apply a 5.00 N force on a syringe plunger that has a diameter of 2.00 cm

Answer 1

The pressure created when you apply a 5.00 N force on a syringe plunger that has a diameter of 2.00 cm is 7961.78 $\frac{N}{m^2}$.

Solution:

Pressure = $\frac{force}{area}$

P = $\frac{5}{\pi \times\ 0.02^2}$

P = 7961.78 $\frac{N}{m^2}$

What is pressure?

• The force perpendicular to an object's surface that is delivered per unit area over that force is known as pressure (symbol: p or P). Gauge pressure, often known as gage pressure, is the pressure in relation to the surrounding air pressure.
• To express pressure, a variety of units are employed. The SI unit of pressure, the pascal (Pa), for instance, is equal to one newton per square meter (N/m2).
• The pound-force per square inch (psi), on the other hand, is the traditional unit of pressure in the imperial and U.S. customary systems. Standard atmospheric pressure (atm) is another way to express pressure; it is the same as atmospheric pressure.
