fabrication of solar powered automobile air cooler abstract

Abstract

At present, solar vehicle is used as one of the cardinal energy saving vehicle where the application of renewable energy meets sustainable energy demand with reduction of fuel cost plus purification of atmosphere. In this vehicle, solar energy powers all or part of a vehicle's propulsion. For running a model car or toy car which is a miniature representation of an automobile, electric power is needed to run the car. As there lies shortage of electric power in Southeast Asian ....etc

Abstract

The differential pressure method is widely used nowadays for air leak detection. In this method, a master tank, which is leak-tight, a tested tank are simultaneously charged to a certain pressure and then closed off each other. If there is air leak in the tested tank, the air leak can be detected from the different pressure occurs between the two tanks. Since both tanks temperature is inconsistent in detection process will lead to changes in pressure affect the detection precision. Although, if the tested tank is leak-tight. This ....etc
