System Description
Tesca Thermal Conductivity through Metal Bars Apparatus consists of a test material bars viz. Brass & stainless steel whose one end is heated by an electrical heater and the other end is kept in a cooling water chamber which acts as heat sink. The test section i.e. intermediate of the bar is well insulated within a shell of asbestos powder to minimize the radial heat loss. Separate thermocouples have been provided to measure the radial heat loss. Two separate radial specimens with an arrangement of a central heater and ring heater to be sandwiched between them have been provided. A heat sink is provided with water circulation arrangement. This setup is properly insulated ‘Tesca’ has design the system having features of ease to operate; demonstrated & perform requisite experiments
