The equation relating thermal energy to thermal mass is = where Q is the thermal energy transferred C th is the thermal mass of the body and ΔT is the change in temperature.. For example if 250 J of heat energy is added to a copper gear with a thermal mass of 38.46 J/°C its temperature will rise by 6.50 °C.

• ### Finding Moisture in Buildings Using Thermal Imaging

Feb 01 2011 · With our thermal imager we were able to see the radiant heating in the slab very clearly but did not identify any areas indicative of a leak. When we imaged the openings in the wall we were able to identify a trough that went around the basement slab. This trough was installed by the builder to catch any basement wall leakage that may occur.

• ### Mould Core Material for the Steel Foundry ScienceDirect

The parts near the metal interface will expand more than those inside the mould wall because of the temperature gradient existing. If a single crack appears the casting shows defects known as buckles or rat-tails. Scab defects are more common with green synthetic sands than dry or silicate–CO 2-bonded sands. It is assumed that the moisture
