What type of reaction is CH4 2 O2 → CO2 2 H2O? The combustion of methane or octane is exothermic; it releases energy. CH4 + 2 O2 → CO2 + 2 H2O + energy The energies of the products are lower than the energiies of the reactants. What type of reaction is CH4 2O2 → […]
Is a refrigerator an open or closed system?
What is the working principle of Venturi meter?
What is the working principle of Venturi meter? The principle behind the operation of the Venturi flowmeter is the Bernoulli effect. The Venturi measures a fluid’s flowrate by reducing the cross sectional flow area in the flow path and generating a pressure difference. What is Venturimeter explain its construction and working? Venturimeter is work on […]
What is meant by supercharging?
What is meant by supercharging? A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. Power for the supercharger can be provided mechanically by means of a belt, shaft, or chain connected to the engine’s crankshaft. What is scavenging in IC engine? Scavenging is the […]
How does grain size affect the properties of a metal?
How does grain size affect the properties of a metal? Grain size has a measurable effect on most mechanical properties. Also, fine-grain steels have greater fatigue resistance, and a fine grain size promotes a somewhat greater tough- ness and shock resistance. Steels made fine grained by addition of aluminum have machinability inferior to those made […]

Why structure properties use relationship is considered very important in engineering materials?
Why structure properties use relationship is considered very important in engineering materials? A material in a product possesses a set of properties—strength, hardness, conductivity, density, colour and so on—chosen to meet the design requirements. The structure property relationship (Table 1.2) gives the material engineer a basis for understanding the nature and behaviour of a wide […]
