How many watts is a light bulb? 60 How much energy does it take to power a lightbulb? We will also assume that a kWh of energy costs 15 cents. Incandescent: A 100-watt, classic light bulb running for a full year would use up 876 kWh of energy. This means a full year of running […]
What is a Level 4 process?
What is a Level 4 process? Level four: is the documentation of systems, instructions and procedures required to complete steps in the level three processes and shows inputs, outputs, associated steps and decision points. The procedures and system instructions can be represented as text, an algorithm or detailed process map. What does ISO stand for […]
How can a force be resolved into its perpendicular components?
How can a force be resolved into its perpendicular components? In two dimensions, a force can be resolved into two mutually perpendicular components whose vector sum is equal to the given force. The components are often taken to be parallel to the x- and y-axes. Let F be a force, of magnitude F with components […]
What is the function of the turbine in the power plant?
What is the function of the turbine in the power plant? The gas turbine is the engine at the heart of the power plant that produces electric current. A gas turbine is a combustion engine that can convert natural gas or other liquid fuels to mechanical energy. This energy then drives a generator that produces […]
What is load factor of motor?
What is load factor of motor? Load factor is an expression of how much energy was used in a time period, versus how much energy would have been used, if the power had been left on during a period of peak demand. It is a useful indicator for describing the consumption characteristics of electricity over […]
What are the four protective coatings used on aluminum?
What are the four protective coatings used on aluminum? 5 corrosion resistant metal coatings compared Anodising. The most popular method of improving corrosion resistance on aluminium is anodisation. PEO. Plasma Electrolytic Oxidation (PEO) involves the use of plasma discharges to transform the metallic surface of light metals. Chromate conversion coating. Paints. Powder coats. What is […]
What is a rosette strain gauge?
What is a rosette strain gauge? A strain gauge rosette is a term for an arrangement of two or more strain gauges that are positioned closely to measure strains along different directions of the component under evaluation. How does a strain gauge rosette work? Strain Gauge Rosettes The rosettes are used to determine the complete […]
What is the difference between conduction convection radiation and evaporation?
What is the difference between conduction convection radiation and evaporation? Conduction transfers heat from one object to another through physical contact. Convection transfers heat to air or water. Radiation transfers heat via infrared radiation. Evaporation transfers heat as water changes state from a liquid to a gas. What is the difference between convection and conduction […]
How does convection flow?
How does convection flow? Convective heat and mass transfer takes place both by diffusion – the random Brownian motion of individual particles in the fluid – and by advection, in which matter or heat is transported by the larger-scale motion of currents in the fluid. How does convection work in fluids? Convection occurs when particles […]
