          Product Code : SSITH-036
          Brand Name : Saini
          Product Description

          consists of a centrifugal blower which delivers  the required quantity of air. The air passing through the pipe is heated by an electrical heater. The temperatures of air entering and leaving heating section are measured by thermocouples. By knowing heater input and mass flow of air, (which is measured with the help of an orifice and water manometer) specific heat of air at constant pressure can be calculated. The test section is well insulated to minimize the heat losses. Silica get is provided at blower delivery to reduce the effect of moisture content in air. In order to determine the specific heat of air at different temperatures air quantity and heater input can be varied.
