SCI 101 DrG Pressure week 9

Front

What is pressure?

Back

Pressure is defined as the force applied per unit area, typically measured in pounds per square inch (psi).

Front

What is the formula for calculating pressure?

Back

The formula for calculating pressure is P = F/A, where P is pressure, F is force, and A is area.

Front

If a force of 50 pounds is applied to an area of 0.5 square inches, what is the pressure?

Back

100 psi.

Front

What is Pascal's Law?

Back

Pascal's Law states that an external pressure applied to a fluid in a closed vessel is uniformly transmitted throughout the fluid.

Front

If a force of 100 pounds is applied to a piston with an area of 4 square inches, what is the pressure?

Back

25 psi.

Front

How do you calculate the total force from pressure and area?

Back

The total force can be calculated using the formula F = P x A.

Front

If 80 pounds per square inch of pressure is applied to a 2 square inch area, what is the total force?

Back

160 lbs.

Front

If total force is 120 pounds and pressure is 30 pounds per square inch, what is the area?

Back

4 in squared.

Front

What units are commonly used to measure pressure?

Back

Common units for measuring pressure include pounds per square inch (psi), pascals (Pa), and atmospheres (atm).

Front

What is the relationship between force, area, and pressure?

Back

Pressure is directly proportional to force and inversely proportional to area.
