Pneumatics Final Exam Questions and Answers 100% Pass

Pneumatics Final Exam Questions and Answers 100% Pass How is the force applied to a confined fluid distributed within the fluid? The intensity of the applied force is distributed evenly throughout the fluid as pressure. What is sacrificed when force is amplified in a fluid power system? Distance is sacrificed in the process of force multiplication. What does an actuator do with fluid pressure in a pneumatic system? An actuator converts fluid pressure into mechanical force. On a vacuum gauge reading 6 inches of mercury at sea level, what is this equivalent to on the absolute scale? This reading is equivalent to 24 inches of mercury on the absolute scale. Which pressure gauge type is generally more accurate: bourdon tube or plunger type? The bourdon tube gauge is typically more accurate than the plunger type gauge. 2 What does an intensifier do in terms of fluid pressure? An intensifier increases the pressure of the fluid. What is the equivalent of atmospheric pressure in inches of mercury vacuum? 29.92 inches of mercury vacuum is equivalent to atmospheric pressure. When a gas’s volume is decreased by compression, what happens to its pressure and temperature? The pressure of the gas increases, and its temperature also rises. How do the molecules in hot gas compare to those in cooler gas? Molecules in hot gas move faster compared to those in cooler gas. In a pneumatic system, what transformation occurs with the potential energy of compressed air? The potential energy of compressed air is converted into kinetic energy and heat. How is flow rate measured in a pneumatic system? Flow rate is expressed in cubic feet per minute (CFM). 3 What occurs to gas pressure and temperature when its volume expands? Both the pressure and temperature of the gas decrease. What happens to fluid flow in a pneumatic system when air is allowed to expand? Fluid flow occurs when air is allowed to expand. What are common causes of inefficiency in a pneumatic system? Inefficiencies typically result from friction, changes in fluid direction, and heat generated by compression. What defines standard air conditions? Standard air is defined as air at sea level with a temperature of 68°F and a relative humidity of 36%.
