About This Product
Liquid from the constant-level head tank flows steadily along the glass tube past the heated coil until a steady temperature state is reached. The electrical energy given to the coil is then compared with the heat gained by the flowing liquid. The felt-lined wooden housing encloses the tube, and the element can be taken out for inspection and resistance measurement.
Frequently Asked Questions
What does the apparatus measure?
It measures the specific heat capacity of liquids and the mechanical equivalent of heat (J) by the continuous flow method.
How is the flow kept steady?
A constant-level brass head tank on a stand feeds the liquid and keeps a uniform pressure head.
