Heat Engine Cycle: When the air chamber is moved from the cold water bath to the hot bath, the piston rises, lifting the 200 g mass to demonstrate work. (e) The air chamber is placed back into the ice water. In stage C, the air chamber can was transferred to the hot bath without removing the test object. 0000050925 00000 n

From this diagram, the heat added to the gas and the work done by the engine are measured to determine the efficiency of the engine. 0000077065 00000 n
The pressure sensor measures the absolute pressure in the cylinder, P, in kPa. A 99.53% difference between thermodynamic and mechanical work means that there are sources of error. The can is moved from the cold bath to the hot bath. 0000037652 00000 n

Design and create a thermodynamic system consisting of a flask, tubing, syringe, and pressure sensor. The goal of this laboratory experiment was to observe an actual model for steam power and evaluate how the heat engine performs and the requirements that are needed in order for the heat engine to extract heat from a hot source and reject heat to a cold sink in order to produce a work output.
