A measure of the total amount of dissolved matter in water.
Total expense ratio
Percentage of monthly debt obligations relative to gross monthly income.
Total harmonic distortion (thd)
A measure of the distortion of the sine wave on alternating current (ac) systems caused by higher order waves superimposed on the fundamental (usually 60hz) frequency of the system. Thd is expressed in percent and may refer to individual electrical loads (such as a ballast) or a total electrical circuit or system in a building. The ansi recommendation is for thd to be no greater than 32% although some electrical utilities may require lower thd's on some systems. Excessive thd's on electrical systems can cause efficiency losses as well as overheating and deterioration of system components.
Total head
The difference between the head at the discharge and suction flange of the pump ( syn Total Dynamic Head, pump head, system head).
Total heat
The sum of the sensible and latent heat in a substance or fluid above a base point, usually 32 degrees Fahrenheit.
Total home comfort system
The ultimate solution to providing you with consistent, customized home comfort, despite the ever-changing weather.
Total incident radiation
The total radiation incident on a specific surface area over a time interval.
Total internal reflection
The trapping of light by refraction and reflection at critical angles inside a semiconductor device so that it cannot escape the device and must be eventually absorbed by the semiconductor.
Total lender fees

Total loan amount
