Why use mcq intercooled multi-stage compression?
Why use multi-stage compression with intercooler? Explanation: For these reasons, we must use multi-stage compression with intercooling.Explanation: here p1 is the evaporator pressure, p2 is the condenser pressure. Explanation: These are a group of halogenated hydrocarbons.
Why use multistage compression Mcq?
Why use multilevel compression? a) Improve COP description: Refrigeration can be improved by expanding the refrigerant to a very near saturated liquid state. The overall work can be reduced if the refrigerant is compressed by multi-stage compression very close to the saturated vapor line.
When using water intercooling in multistage compression, the Mcq?
water cooling Reduce the work to be done in low pressure compression. Description: Water intercooling reduces the work done in high pressure compression.
What is the role of the multi-stage circulating Mcq intercooler?
In a two- or multi-stage air compressor, the intercooler is always placed between the low pressure (LP) and high pressure (HP) cylinders.The purpose of the intercooler is to The work input to the compressor is reduced to achieve the same pressure as a single compressor can.
What is the use of multi-stage compression in refrigeration system?
The advantages of multi-stage compression are:
4) Reduced heat removal during condensation Therefore, the size of the condenser is reduced. 5) The volumetric efficiency of the compressor is improved due to the reduction of the pressure ratio of each stage. 6) The temperature at the end of compression will be lower.

Why do you need multiple levels of compression?
Temperature Control Required: Multi-Stage Compressor Air temperature can be adjusted. Because they cool the air as it passes through each chamber, the output air is cooler. Choose a multi-stage compressor when heat can damage or reduce the efficiency of pneumatic equipment.
What are the advantages of multi-stage compression over single-stage compression?
Advantages of multi-stage compressors over single-stage compressors. –Fluids can be compressed to very high pressures. – The intercooler cools the cylinder walls more efficiently than in single-stage compressors. – Reduced pressure ratio per stage, reducing leakage loss.
What is the role of the intercooler Mcq?
Explanation: The intercooler is The heat exchanger removes heat from the compressor. Description: The intercooler reduces excess heat from the compressor and increases volumetric efficiency. Explanation: By using an intercooler, the amount of intake air is reduced, thus reducing fuel knock.
Why do we need to do intercooling?
Intercooler is a Method for compensating for heat generation caused by supercharging, a natural by-product of the semi-adiabatic compression process. The increased air pressure causes the intake air to overheat, significantly reducing the performance gain of boost due to reduced density.
Do you use multi-stage compression with intercooling?
12. Why use multi-stage compression intercooling? Explanation: For these reasons, we must use multi-stage compression with intercooling. Explanation: Here p1 is the evaporator pressure and p2 is the condenser pressure.

What happens when water cooling is used in multistage compression?
Water cooling is usually used in air compressors. Intercooler not only reduces work input, but also lowers compressor discharge temperature for better lubrication and longer compressor life.
When the size of the smallest hole is larger than the size of the largest shaft, what is it?
Explanation: When the minimum hole size is greater than the maximum shaft size clearance fit. Explanation: The minimum clearance is the difference between the minimum hole size and the maximum shaft size.
Which nozzle does the rocket motor Mcq use?
Explanation: The nozzles used in blast furnaces are called tuyere. Explanation: Subsonic flow if M<1. Explanation: In a rocket, air flows first from the converging segment and then from the diverging segment.
What is the function of the aftercooler?
An aftercooler is a mechanical heat exchanger designed to Remove the heat of compression from the compressed air stream and prepare the air so that it can then enter the dryer and/oror for pneumatic equipment.
Which of the following is not an advantage of water intercooling when used in multi-stage compression?
Which of the following is not an advantage of compound vapor compression with intercooler?Description: One of the advantages of using an intercooler for compound vapor compression is that it provides a more uniform torque and therefore a smaller size flywheel is needed.
Will a bigger intercooler increase turbo lag?
However, it should be noted that an oversized intercooler can actually do more harm than good.if you have a Huge intercooler and you’ll cause more turbo lag And more resistance inside the whole system.
Why do gas turbines use intercoolers?
Adding an intercooler to the gas turbine cycle reduce compressionthis is achieved by dividing the compression process into two or more stages, the outlet air/gas of each stage is cooled to the minimum cycle temperature by an intercooler/heat exchanger.
What’s in the intercooler?
Intercooler is a heat exchanger Installed between the engine’s super or turbocharger and the intake manifold. Its job is to absorb and dissipate heat from the charge air in order to provide the coldest and densest air to the engine. There are two types of intercoolers, air-to-air and water-to-air.
How did OTEC come about?
Ocean Thermal Energy Conversion (OTEC) is a Generates energy by exploiting the temperature difference (thermal gradient) between the ocean’s surface water and deep ocean water. Energy from the sun heats the ocean’s surface water.
What is the main purpose of using an intercooler with a compressor?
The function of the intercooler
The main function of the air compressor intercooler is to Cool the air before it enters the next compression stage. The higher density of cold air makes it easier to compress than hot air. Ideally, the air should be as close to the ambient air temperature as possible.
Which is the most preferred SI engine fuel?
The most preferred motor fuel is paraffin and for SI engines the most preferred fuel is Aromatic hydrocarbons.
Why are multi-stage compressors better than single-stage?
Advantages of multi-stage compressors over single-stage compressors. Fluids can be compressed to very high pressures. The intercooler cools the cylinder walls more efficiently than in single-stage compressors. … for a given pressure ratio, the multi-stage arrangement improves volumetric efficiency.
What is your understanding of multistage compression?
Multi-stage compression: Multi-stage is Simply compress air or gas in two or more cylinders instead of a single-cylinder compressor…for isothermal compression and expansion processes, the loss during compression is equivalent to the compression work and no intercooler is required.
What is the difference between a single-stage pump and a multi-stage pump?
Multistage pumps are centrifugal pumps in which fluid flows through multiple impellers mounted in series.This is the same as having only an impeller. The more stages the pump has, the higher the final discharge pressure.
