This paper is a lab report for an experiment on the calibration of a differential pressure transducer. Through this experiment, we will be able to measure the accuracy of the differential pressure transducer. Ideally, this equipment works in accordance with the principle of static differential pressure measurement. The pressure transducer...

1. Thermal Physics 1.1 Change of Pressure with Altitude and Temperature p = Given, T = T0 –az; (K) for z 11,000 m a = 0.00649 K/m a) From the equations of the aerostatic and the perfect gas law, we can write, p = ρ R...

(a) An AC voltage is described by the equation 푣 (푡) = 푉cos(휔푡 + 휙). Sketch this voltage waveform, and explain the meaning of terms 푉, 휔, 푡 and 휙. Sketch of the voltage waveform. V   The maximum or peak value of the voltage 휔   the angular frequency expressed in radian...

Newtonian laws have become a handful in illustrating the relationship between forces and motions. The type of relationship that exists between the two is counter-intuitive and as such needs a careful review as well as an explanation. The first law suggests that a body will remain static or continue in...

According to Christensson (2016, par 1), a diode is an electrical component that is designed for unidirectional conduction of electric current. A diode has two terminals with each end having an electrode that bears a different charge. One side of the terminal referred to as, an anode, has a positive...

Reduction in personal carbon footprint (subtract row C from row B)(tonnes CO2e/year) 0.10 0.05 0.07 0.07 00.24 E Will this change cost me a lot of money up front? No. No No I can afford the cost I guess, yes. F Will this change save me money in the long term? A...

Outline and discuss the difference between critical theory and problem solving theory. In regards to our view to the world order, Critical theory stands apart from the predominant order of the world and questions the origin or background of the order and how it came into existence while on the other...

Numerous hypotheses have been proposed to discover why there exists a huge gap between the possession of environmental knowledge and the exhibition of pro-environmental behavior. Despite the existence of numerous studies, no exact explanation has been developed. One needs to evaluate some of the reasons which cause people to either...

Fossil fuels, especially coal, were the primary source of energy in the industrial revolution. Their usage continues to date with petroleum and natural gas as the main fuels for heating, agriculture, transport, and manufacturing. Currently, all material aspect of life depends on fossil fuels. There are negative impacts at every...

The social reaction or labelling theory focuses on the negative linguistic characterisation or tendency embraced by a majority group to a minority group based on the deviance from social norms. According to the theory, self-identity, as well as the behaviours of individuals, may be influenced or determined by the perspective...

The rapid increase in the usage of hand-held devices by drivers in various states in the United States has led to growing public concern over road safety and the impact on the performance of the driver (Jacobson 1586). Over the last two decade, wireless subscriber connections in the United States...

Climate change is one of the major challenges facing the world in the 21st century. Scientists and environmentalists believe that the problem poses a significant danger to humanity. For the same reason that climate change is not friendly for human survival, scientists and environmentalists advocate for appropriate steps in addressing...
