How heat transferred in solid materials
WebConductive Heat transfer (Qc) = – K A (dT / L) Where ( dT / L) is known as temperature gradient. Its value is always negative because the temperature gradient vector is in the opposite direction of heat flow. Conduction heat transfer is more significant in solid bodies and it follows the first law of thermodynamics. WebHOW IS HEAT TRANSFERRED? RE ACH.
