Question

dampers aren't operating properly in lynn's hvac system. the repairwoman checks the pneumatic pressure and reads that it's 20 psi. this indicates that the psi is:_______

Answer 1

A pressure reading of 20 psi in an HVAC system is a gauge reading that indicates the force per unit area. This needs to be compared with the system specifications to determine if it's within the proper range.

Step-by-step explanation:

When the repairwoman checks the pneumatic pressure in Lynn's HVAC system and finds it to be 20 psi, this is a reading from a gauge that indicates the force per unit area within the system. Gauges are designed to measure the pressure and convert it into a readable value. If the dampers are not operating properly, the 20 psi reading may be either too high or too low, depending on the design specifications of the HVAC system. It's vital to compare this reading against the normal operating pressure range specified for the system to determine if it is within the acceptable range or if an adjustment or repair is needed.
