In engineering, performance curve may refer to: Load testing curve, in software testing. Thrust curve, in rocketry. This page was last edited on 26 ...
Pump curves are quite useful in the pump selection, testing, operation and maintenance. Pump performance curve is a graph of differential head against the operating flow rate. They specify performance and efficiency characteristics. Performance tests are done on the pumps to verify the claims made by the pump maker.
Performance of a compressor is usually specified by curves of delivery pressure against mass flow rate for various fixed values of rotational speed and inlet temperature. [2] [3] [4] These performance characteristic curves are usually plotted with dimensionless variables.
The Yerkes–Dodson law is an empirical relationship between arousal and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in 1908. [1] The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases.
This Figure shows the Performance Curve for Axial Flow Fan. [1] The relationship between the pressure variation and the volume flow rate are important characteristics of fans. The typical characteristics of axial fans can be studied from the performance curves. The performance curve for the axial fan is shown in the figure.
A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.
The blue dots on the curve represent maintenance actions. Pavement performance modeling or pavement deterioration modeling is the study of pavement deterioration throughout its life-cycle. [ 1 ] [ 2 ] The health of pavement is assessed using different performance indicators.
The thermodynamic method is used for performance testing of pumps, flow meter calibration, system curve tests, and other applications. It is capable of achieving results with uncertainties of less than 1% in pump efficiency and less than 1.5% in flow [ 3 ] while being able to test piping configurations where other conventional pump testing ...
