Answer :

Final answer:

option(C).

Service hoses used with R410a equipment must be rated to c) 500 psi. Proper pressure rating is essential for safety and efficiency in HVAC applications.

Explanation:

In HVAC (Heating, Ventilation, and Air Conditioning) industry, the use of service hoses is essential. These hoses are used in various operations, particularly with different types of refrigerant gases such as R410a. It's crucial that these hoses be rated appropriately for the pressure they carry to ensure safety and optimum performance. For R410a equipment, it is generally recommended that the service hoses be rated to c) 500 psi.

The conversion figures in the reference information given, such as 101.5 kPa being approximately equal to 14.7 psi, can be applied in situations where pressure values need to be converted from one unit to another. For instance, 1 atmosphere (atm) is about 14.7 psi, and 1 bar equals 100 kPa or about 14.5 psi. It's important to understand these values when working with pressure systems, particularly in HVAC applications.
