70% to passWhen performing a hydrostatic test on a low pressure evaporator to determine the source of suspected air leaks you should use _______________.
Afresh water at or above the ambient temperature
Bair and a soap solution to test all joints
Cphosphorescent hydrazine bisodium solution visible under a black light source
Dcirculated cold fresh water, while maintaining all normal unit operating pressures
AI Explanation
The correct answer is A) fresh water at or above the ambient temperature. When performing a hydrostatic test on a low pressure evaporator, fresh water at or above the ambient temperature is used to test for air leaks. This is because water at the appropriate temperature can effectively identify any leaks in the system's joints and connections without the risk of damage associated with using other test mediums like air or chemicals. The other options, such as using air and soap (B), a specialized chemical solution (C), or cold water (D), are not the proper methods for conducting a hydrostatic test on a low pressure evaporator.
