Chapter 7, Problem 1RQ
The standard weight of copper tubing used most frequently in the heating and air-conditioning industry is
A. K.
B. L.
C. DWV.
D. M.
Expert Solution & Answer
To determine
Most frequently used weight of copper tubing
Answer to Problem 1RQ
L type copper tubing is most frequently used, therefore answer B.
Explanation of Solution
The copper tubing is available in four standard weights. They are K, L, M and DMV.K type copper tubing is used for heavy duty applications.M and DMV are light weight tubing which are not frequently used in HVAC/R industry.The L type copper tubing is the one which is used frequently and has medium amount of weight.
