REVIEW QUESTIONS 1. (a) What are the reasons for considering the use of pneumatic systems instead of hydraulic systems? (b) What are the major drawbacks of using pneumatic systems. (c) How can you select a fluid medium for a given application. 2. With a simple sketch, explain the functions and working of basic components required for a pneumatic system. (or) Draw the layout of the complete pneumatic system and explain its subsystems. [A.U., May/June 2006; Nov/Dec 2016] [Ans. Refer Section 10.4] 1. The atmospheric air is compressed by an compressor to 1/5th the volume. What is the gauge pressure of compressed air, assuming the temperature does not change. [Ans. 5 bar] 2. 500 cm3 of air at temperature 30°C, contained in a cylinder, is heated at constant pressure to a temperature of 70°C. Calculate the increase in volume of air? [Ans. 66 cm3] 3. Air is contained in a cylinder at P1 = 3 bar gauge, and T1 = 25°C. If the air is heated to 80°C without changing its volume, what is the new pressure of the air? [Ans. 3.74 bar gauge] 4. Gas at 50 bars gauge and 60°C is contained in the 0.75 m3 cylinder. The gas is compressed to the volume of 0.6 m3 and the temperature increases to 130°C. What is the final pressure of the gas? [Ans. 76.15 bars gauge] PROBLEMS FOR PRACTICE
