Chapter 7, Problem 1R
Using Table 7-1, list the six different fuel gases in rank order according to their temperature.
Expert Solution & Answer
To determine
List the six different fuel gases in rank according to their temperature according to Table 7-1.
Explanation of Solution
In cutting process various gases are used. Oxyacetylene gas is the most common gas which is used to cut the metal. Some of the other gases are given below according to their temperature given in table 7-1:
| Ranking position | Fuel gases | Temperature ( Celsius ) |
1 | Acetylene | 3087 |
2 | MAPP | 2928 |
| 3 | Propylene | 2868 |
4 | Hydrogen | 2660 |
5 | Natural gas | 2536 |
| 6 | Propane | 2526 |

(a) State the conditions that must be met to ensure dynamic balance is achieved for long rotors.
(b) A rotor carries three out-of-balance discs in planes A, B and C as shown in Figure 4. The out-of-
balance mass x radius products of the rotor discs are tabulated in Table 4.
The shaft is to be dynamically balanced by adding balancing masses in planes P and Q, spaced along
the shaft at a distance da = 800 mm.
Determine the magnitude mara and angular position of the balancing mass x radius product that
must be added to plane Q.
