What the difference between extraction and bleeding in steam turbine?
bleed is amount of steam output from turbine through pipe and exit from final stage of turbine . this bleed enter to feed water heater (low and high) and deaereator to increase unit efficiency or rather bleed is the amount of steam drained out of the steam turbine during the expansion of steam and this rejected heat energy is used to heat the feed water supplied to the boiler...........
What are the Main parameters that affect the injection molding process?
Following parameters affect injection moulding process. 1) nature of material (type of plastic) 2) rate of injection 3) size of the component being moulded 4) efficiency of machine 5) type of cooling method adopted 6) curing time in the mould
Loading unloading valve working of screw compressors?
Pressure regulation is accomplished by the use of free air unloading.The purpose of such control to unload theair compressor.When more air is being compressed than is being consumed.Thus reducing to a minimum the power required to drive the compressor and providing maximum economy during the unloading period.This control was done by manual operated type unloaders such as "M" type or "W" type unloaders.Actually this is old technology and replaced by "Electro-Pneumatic Controls" which is also replaced by "Program Logic Control".Still many companies are using old technology and therefore,I am giving details about "M" Type Unloader. * The operation of the unloader is simple and positive.When the pressure in the airdischarge line from the compressor to the receiver reaches the pressure point at which the unloader is set to operate,as determined by the position of the adjusting screw,the plate valve is forced away from its seat on the unloader body.When this happens,air from the discharge line from the compressor to the receiver passes through the unloader and to the unloading suction valve covers,holding these valves open.Then the compressor operates against the atmosphere pressure only. * When the air pressure in the discharge line from the compressor to the receiver is reduced to the predetermined pressure setting of the unloader as determined by the number of unloader shims,then the compression of the spring,over-comes the pressure of the air in the discharge line from the compressor acting against the plate valve,forcing the valve back against its seat on the unloader body.The air trapped in the unloader piping is then vented out to the atmosphere through the vent hole of unloader. * The pressure at which the unit will unload is determined by the position of the adjusting screw.Turning this screw in,increase the compression pressure on the spring and the unloading pressure of compressor.Turning the screw out,lower the unloading pressure.To decrease the loading-unloading range,add the shims and to increase the range,remove the shims. * The most important care that the unloader should receive is to be kept clean.If the operation of it becomes sluggish,the operator should first make sure that all unloader piping is free from leakages since leakage from these places will affect the operation of the unloader.Also the vent hole in the unloader valve seat is open.The gauze of the air cleaner in the unloader line should be removed and cleaned.If problem is not solved,remove the unloader valve seat and clean.If the cleaning and adjusting fail to make the unloader operate satisfactorily,the valve may require grinding. * Use fine grinding compound for valve seat grinding.The valve is provided with two small holes on the top surface for the insertion of the tool to turn it in grinding.Avoid excess grinding since this may change the point of contact sufficiently to affect operation adversely.Clean out all the compound thoroughly after grinding.
Does ambient temp effect the temperature produced by an air conditioning unit?
In short answer, yes. There are many things that will affect the temperature produced by an air conditioning unit, to be honest.
Describe the regulations that affect how they should be treated at work (such as Equal Opportunities Act Race and Sex Discrimination Working Time Directive)?
Discrimination is when someone is treated differently
How many types of compressor problem?
There are primarily three types of compressor problems: mechanical issues, operational inefficiencies, and control system failures. Mechanical issues can include wear and tear, leaks, or component failures. Operational inefficiencies often arise from improper sizing, incorrect settings, or inadequate maintenance. Control system failures can involve sensor malfunctions or software errors that affect compressor performance.
Is it correct to consider the compressor capacity as the capacity at inlet?
No, it is not entirely correct to consider compressor capacity solely as the capacity at the inlet. Compressor capacity typically refers to the amount of air or gas that can be moved or compressed by the compressor, which is often measured at the outlet under specific conditions, such as pressure and temperature. Inlet conditions can affect performance, but the capacity is more accurately defined by the discharge conditions and the efficiency of the compressor system.
How does mass effect efficiency?
Mass can affect efficiency by influencing the amount of force or energy required to produce a certain result. In some cases, greater mass may cause inefficiencies due to increased resistance or workload. However, in other cases, optimizing mass distribution can actually improve efficiency by enhancing stability or balance.
How do low winds affect the efficiency of wind turbines?
Low winds can reduce the efficiency of wind turbines because they generate less power when there is not enough wind to turn the blades at a sufficient speed. This can result in lower electricity production and decreased overall performance of the wind turbine.
What are the factors that will affect the electrical energy output from the turbine?
The science of measurement of visible light in terms of its perceived brightness to human vision (optics).The measurement of the flux or intensity of an astronomical object's electromagnetic radiation (astronomy).
What is the effect on a steam turbine if the system is running in under frequency?
It results in reduced ventilation and affect the turbine more than the generator.
What is impact of centralization on manpower efficiency?
centralization inversely affect manpower efficiency
What factor determines how much electricity a windmill produces?
The main factors that determine how much electricity a windmill produces are the wind speed and the size of the wind turbine's rotor blades. Higher wind speeds and larger rotor blades can generate more electricity. Other factors that can affect electricity production include the efficiency of the wind turbine and the maintenance of the system.
What is the relationship between Pareto efficiency and externalities in economic theory?
In economic theory, Pareto efficiency refers to a situation where resources are allocated in the most efficient way possible, maximizing overall societal welfare. Externalities are costs or benefits that affect parties not directly involved in a transaction. The relationship between Pareto efficiency and externalities is that externalities can lead to market inefficiencies and prevent the achievement of Pareto efficiency. This is because externalities can result in a misallocation of resources and a failure to account for the full costs or benefits of a transaction, leading to a suboptimal outcome for society as a whole.
Does cutoff ratio affect the engine efficiency?
yes
Does heat affect efficiency of a wedge?
I highly doubt it.
