SCI 101 DrG Pressure week 9

Front

What is the formula to calculate pressure?

Back

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

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 is the relationship between force, pressure, and area?

Back

Force is equal to pressure multiplied by area (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

What is the formula to calculate area when force and pressure are known?

Back

A = F / P.

Front

If we have 50 pounds of force applied to an area of 0.5 square inches, what would be 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 in a hydraulic cylinder of 4 square inches in area, what is the pressure?

Back

25 psi

Front

What is the unit of pressure in the imperial system?

Back

Pounds per square inch (psi).

Front

How do you convert pressure from psi to pascals?

Back

1 psi = 6894.76 pascals.
