Water warms up as it flows through the fully assembled solar collector. The temperature increase is a function of the flow rate of the water.
Principle
The solar ray collector is illuminated with a halogen lamp of known light intensity. The heat energy absorbed by the collector can be calculated from the volume flow and the difference in the water temperatures at the inlet and outlet of the absorber, if the inlet t ...
Pressures and temperatures in the circulation of the heat electrical compression heat pump are measured as a function of time when it is operated as a water-water heat pump. The energy taken up and released is calculated from the heating and cooling of the two water ...
A model house with replaceable side walls is used for determining the heat transition coefficients (k values) of various walls and windows and for establishing the heat conductivities of different materials. For this purpose the temperatures on the inside and outsid ...
The Stirling engine is submitted to a load by means of an adjustable torquemeter, or by a coupled generator. Rotation frequency and temperature changes of the Stirling engine are observed. Effective mechanical energy and power, as well as effective electrical power, ...
Sodium acetate trihydrate can form supersaturated solutions. Spontaneous crystallizing out of these leads to an increase in temperature. The change in temperature over time that occurs during this process can be experimentally examined.
