Callendar & Barne's Apparatus ( Continuous Flow) Manufacturer,Supplier and Exporter in India
Product Code : EL-AP-11120
The Callendar and Barnes' Apparatus is a high-precision
thermodynamic instrument designed for the empirical determination of the
specific heat capacity of liquids and the mechanical equivalent of heat (J) via
the continuous flow method. Engineered for University-level physics and
engineering curricula, it ensures steady-state thermal equilibrium. This system
adheres to ISO manufacturing standards for educational lab equipment.

Key Pedagogical Outcomes
- Continuous
Flow Design: Allows students to achieve a steady thermal state,
eliminating the need for cooling corrections required in static
calorimetry, supporting Advanced Thermodynamics modules.
- Spirally
Wound Nichrome Element: Ensures laminar flow heating profile, enabling
precise calculation of electrical energy input (VI t) versus thermal gain
(mc\Delta\theta).
- Constant-Level
Brass Tank: Maintains a uniform pressure head to ensure a constant
mass flow rate (\dot{m}), essential for Bloom’s Taxonomy
"Analysis" of steady-state energy transfer.
- Detachable
Heating Element: Facilitates direct inspection of component wear and
resistance measurement, allowing for the practical evaluation of Joule
heating principles.
International Logistics & Compliance
