Textbook Problem

Use Table 31-4 to determine which fuel gas has the highest burning velocity when mixed with oxygen.

To determine

The highest burning velocity of fuel gas when mixed with oxygen from table Welding: Principles and Applications (MindTap Course List), Chapter 31, Problem 32R


Hydrogen is the lightest element in the periodic table. Hydrogen, when reacts with oxygen produces water and energy. Hydrogen fuel used to generate motive power, for portable fuel cell applications. Hydrogen flame is almost colourless.

Hydrogen has the fastest burning velocity. The burning rate of acetylene is nearly less than the burning rate of hydrogen. Due to lack of availability and expensiveness of hydrogen, it is not widely used for welding. Unlike acetylene, hydrogen reacts in the presence of sufficient oxygen. As hydrogen is lighter than the air, any uncontrolled combustion of a large quantity of hydrogen will occur in an upward direction unlike other which burns in the downward direction...
