the air flow detector using led indicates the presence of air in the space by the variation of resistance and corresponding changes in the voltage. the glowing of led is depends on the presence of air. the large amount of air flow will decrease the resistance. ....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

A good bread should be judged by its volume, bloom, shape, colour, texture, sheen, moistness and flavour. In general, one should examine the external area and the internal (crumb) area of the bread.

Bread faults can occur as a result of a series of small faults interacting together. Some faults may be inter-related yet others are independent. Flour varies in grade, in gluten content and quality. Colour also varies and so does the maltose content. In my bakery, when examining the faults in a loaf of bread, the temperature and timings, methods ....etc

Description.

This circuit can give a visual indication of the rate of air flow.It can be also used to check whether there is air flow in a given space.

The filament of a incandescent bulb is the sensing part of the circuit.When there is no air flow the resistance of the filament will be low.When there is air flow the resistance drops , because the moving air will remove some of the heat generated in the filament.This variations in the resistance will produce variation of voltage across the filament.These variations will be picked up by th ....etc
