Pascal's Law deals with measuring the amount of force that acts on a unit of area. The formula we use to express this is: - ️️F=A x D Volume is the amount of space a fluid occupies. The formula we use to express this is: - ️️V=A x D A gain in mechanical advantage is achieved using: - ️️Different sized pistons and constant pressure Viscosity is - ️️The internal resistance to flow The flash point is the temperature at which a liquid gives off vapor in sufficient quanti...

Hydraulics & Pneumatics Questions and Answers Already Passed How is Pascal's Law used to calculate force per unit area? The formula is: Force = Area × Pressure. How do we determine the volume of a fluid? By using the formula: Volume = Area × Depth. What method provides increased mechanical advantage? By employing pistons of different sizes with a constant pressure. What does viscosity measure? It measures the internal friction against flow. What is the flash point of a...

Hydraulics and Pneumatics Final PASSED Exam Questions and CORRECT Answers Absolute pressure can be used in systems that have vacuums to avoid using a negative number. (T/F) - CORRECT ANSWER- True Changing the angle of the swash plate in a variable-displacement piston pump does not affect the distance of how far back a piston pulls. (T/F) - CORRECT ANSWER- False Bleed-off systems are used when more flow control accuracy and less system efficiency is required. (T/F) - CORRECT ANSWER- Fal...
