SCI 101 DrG Pressure week 9

Front

What is the formula for calculating pressure?

Back

P = F / A, where P is pressure, F is force, and A is area.

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 pounds per square inch.

Front

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

Back

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

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

Back

160 pounds.

Front

How do you calculate total force using pressure and area?

Back

F = P x A, where F is force, P is pressure, and A is area.

Front

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

Back

100 pounds per square inch.

Front

What is the formula for calculating area when force and pressure are known?

Back

A = F / P, where A is area, F is force, and P is pressure.

Front

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

Back

4 square inches.

Front

What happens to pressure if the area is doubled while keeping the force constant?

Back

Pressure is halved.
