What is the effect or reheater in the gas turbine?
1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
Why free surface effect is detrimental in ro-ro ferries?
RO-RO ferries have large open decks (car decks) without any sub division or bulkheads. Hence a small amount of water would be able to impart a significant free surface effect.
What is reheat factor in power plant?
The reheat factor in the steam turbine refers to the Thermodynamic effect on the turbine efficiency. Others factors includes the cumulative heat, and the steam turbine condition curve.
How does eddy current loss effect a transformer?
Eddy currents act to increase the temperature of a transformer's core above ambient temperature, resulting in a loss of energy through heat transfer -thus reducing its efficiency.
What is the significant relationship of the no load loss in excitation current test in transformer?
The no load losses are the losses caused by energizing the transformer. These are constant losses, regardless of loading. This in effect tells you the efficiency of the transformer. (Power in) - (no load losses) = (Power out)
What are the main causes of friction?
the main causes of friction are molecular adhesion,surface roughness,and the plowing effect.
How does the roughness of a surface effect friction?
The rougher then surface the greater the frictional force. When a surface is rough and you put friction to it, it creates sparks while smooth surfaces when friction is added causes a slight stactic shock.
What is in Cooling Fins on A Radiator?
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
How does friction effect work?
As an object (I will use a ball for an example) slides across a surface or terrain it will gradually heat up and slow down due to the composition and features on the surface. Such features include coarseness/roughness. Friction is described in Newtons Three Laws of motion.
What does efficiency do on a pick-axe?
It doesn't 'do' anything. Efficiency measures the effect something has in proportion to the energy required for that effect.
What is the effect of acid value on the working efficiency of a lubricant?
The effect of the acid value is that it enhances the working efficiency of a lubricant.
What three factors effect angle of repose?
The three main factors that affect the angle of repose are particle shape, size distribution, and surface roughness. A particle's shape influences how particles stack together, with angular particles generally forming steeper angles. Smaller particle sizes typically lead to flatter angles, while surface roughness can impact the interlocking and sliding of particles.
What effect does friction have on a machines efficiency?
Efficiency of the machine is reduced due to loss of energy by friction.
What are some words that begin with Ef?
effect...efficiency
How does mass effect efficiency?
The mass affects the efficiency of an object. It adds more weight, which causes more friction. More friction=less efficiency
What has the author John M Buffington written?
John M. Buffington has written: 'Effects of hydraulic roughness and sediment supply on surface textures of gravel-bedded rivers' -- subject(s): Habitat, Effect of sediments on, Fishes, Salmonidae, Sediment transport, Channels (Hydraulic engineering)
What is the effect of cracked diaphragm in transmission?
The effect of a cracked diaphram in transmission is that it reduces the efficiency of the system.
