Mechanical Engineering
In keeping with Cal Poly's focus on physically applying the concepts learned in the classroom, our team of engineering students has compiled a laboratory experiment displaying the basic thermodynamic cycle found in air conditioning systems. This vapor compression cycle is displayed on a visualization board that features all four major components of the system: the compressor, the evaporator, the condenser, and the throttling valve. Students will take measurements of temperature and pressure at each stage in the cycle and also gauge the power draw from the compressor to gain an understanding of how performance and electricity cost come into play …

Efficiency Testing Of An Electronic Speed Controller, Grace Cowell, Matthew Hudson, Marcus Pereira
Mechanical Engineering
This project required the development of a rig that could experimentally determine the efficiency of an Electronic Speed Controller (ESC). The selected design focuses on measuring the losses due to heat from the device and comparing this to its input power. The selected design is a flow rig that utilizes the heat equation q=ṁcpΔT. The rig provides a steady state measurement of the ESC heat output by passing a known mass flow rate of air across the ESC and measuring the temperature difference. It uses a flowmeter to determine ṁ, thermocouples to determine ΔT, and a table lookup to determine …
