Question

the compressed gas association (cga) has changed the withdrawal rate of acetylene, advising not to exceed _ of the capacity of the cylinder per hour during intermittent use, and for full withdrawal of the contents of the cylinder on a continuous basis, not to exceed a per hour flow rate more than _ of the capacity of the cylinder.
a 1/7, 1/10
b 1/7, 1/8
c 1/10, 1/15
d 1/15, 1/20
e 1/10, 1/17

Explanation:

According to the Compressed Gas Association (CGA) guidelines for acetylene cylinder withdrawal rates. For intermittent use, the rate should not exceed \( \frac{1}{7} \) of the cylinder capacity per hour. For continuous full - withdrawal, the rate should not exceed \( \frac{1}{10} \) of the cylinder capacity per hour.

Answer:

A. \( 1/7, 1/10 \)
