Final Answer:
The minimum distance required between an apparatus and the hose clamp is d. 20 ft. (6 m).
Step-by-step explanation:
When applying a hose clamp, it is crucial to maintain a safe distance between the apparatus and the clamp. This ensures that the hose clamp does not interfere with the proper functioning of the apparatus and allows for effective control.
A distance of 20 ft. (6 m) provides an adequate safety margin, reducing the risk of any unintended consequences. This spacing allows for proper installation, operation, and maintenance of the hose clamp without compromising the integrity and functionality of the apparatus it is securing.
