The aim of the Stress Concentration Experiment was to observe the stress concentration factor/feature for a set of mild steel specimens with various irregularities in each sample. These irregularities or “stress-raisers” include any notches and holes which vary in size (radius) and placement on the specimen (edge notches or holes) that may have an effect on the flow of stress.
With the use of a Hounsfield 50 kN electrically operated tensile testing machine and 12 1-mm thick mild steel test samples the experiment shows how any stress-raiser within a sample will affect the distribution or flow of stress within the specimen resulting in a relatively high concentration of stress near any irregularities. Hence, there will be greater stress around …show more content…
The Rankine cycle is then compared and applied to ideal thermodynamics heat engine cycle. The aim of the experiment is to understand the process of a steam turbine power plant and applying it to a T-S diagram. During which efficiencies at each stages of the Rankine cycle would be calculated. The efficiencies obtained from the experiment are rather low due to a number of reasons. The most fundamental reason is that there is escape of steam due to the bearing not being fully airtight. The Carnot efficiency was calculated since the Carnot efficiency preforms as the most efficient heat …show more content…
Within this experiment propane gas was used to heat water. Propane is pumped into the boiler where the water is stored. The temperature and pressure increase boils the water producing steam. The steam valve is then gradually opened to direct it toward the generator. In turn, the blades of the turbine rotate and the Condenser transforms the steam to water which is pumped back into the boiler. The Carnot cycle is a theoretical cycle which operates at maximum efficiency with ideal conditions. Thus, the efficiency of the Rankine cycle (0.0134%) is evidently lower than the Carnot cycle
