How does solubility depends on temperature?
No. When dissolving a solid into a liquid, solubility is higher when the temperature is higher. When dissolving a gas into a liquid, solubility is higher when the temperature is lower.
How can the temperature in the autoclave go above boiling temperature of 212 F?
At higher pressure the boiling point is higher.
What is the principle involved in pressure cooker?
At higher pressures, water boils at a higher temperature. A pressure cooker lets you cook at a higher pressure than regular saucepans so you can have a higher boiling temperature
Which would freeze at a higher temperature the great salt lake or Lake Tahoe?
lake tahoe would freeze at a higher temperature
What is the relation between melting temperature and GC content in DNA?
Primers with more GC content will affect the melting temperature. Higher GC content will have a higher melting temperature.
Reciprocating compressors have?
Reciprocating compressors are positive displacement in machines. However, separable compressors have higher maintenance costs.
What is difference between vacuum pump and centrifugal pump?
A compressor is a piece of equipment that compresses gas either to transfer to a specific location or for a certain process requirement. Compressor are manufactured depending on application and can be class into two basic types; positive-displacement and centrifugal. Integrally geared centrifugal compressors can operate at many times higher speeds than reciprocating compressors. The higher speeds ultimately result in smaller package sizes, requiring a smaller footprint as compared to a reciprocating compressor. The operating speed of a reciprocating compressor is very slow due to mechanical and dynamic limitations. Furthermore, the lower speed of reciprocating compressor lends itself to larger compressor size, heavier weight, and larger plot plan size. Whereas the centrifugal compressor with higher operating speeds results in smaller overall compressor package sizes such as smaller gearing, bearings, seals, lubrication system, and foundation. Smaller packages ultimately lend themselves to saving in lower overall installations as well as lower capital and spare parts costs. Higher reliability is fully attainable with centrifugal compressors. The rotating aerodynamic components (impellers) have no physical contact with the stationary parts (inlet shroud). On the contrary, the reciprocating compressor moving components such as the piston and valves are physically in contact with the cylinder and other stationary components during operation. The physical contact causes wear and tear of both moving and stationary components, which requires constant maintenance. However, a centrifugal compressor operates for many years with continuous service without overhaul maintenance, resulting in less power plant down time. This eliminates loss of product, provides more profit, lowers risk, and results in lower maintenance cost. Overhaul periods are more predictable by analyzing characteristic efficiency and vibration trends. A typical centrifugal compressor overhaul inspection period is more than 7 years as compared to less than 2 years for most reciprocating compressors. In addition to the economical advantages of implementing a centrifugal compressor over a reciprocating compressor, many technical advantages are also evident. The centrifugal compressor discharge pressure can be regulated to less than 0.5% per second. The well-regulated compressor discharge pressure provides very steady supply of fuel to the gas turbine. This is an advantage since it does not cause additional burden to the turbine controls. On the other hand, a reciprocating compressor at best can provide 2% or more of pulsating pressure. Unsteady supply of fuel may cause hardship on the turbine control system. A reciprocating compressor would require an impractically over-sized pulsation bottle to minimize supply pressure pulsation to the level as steady as a centrifugal compressor. Considering there is no physical contact between the centrifugal compressor aerodynamic components, the need for lubrication within the compression components is not required; thus it will not add oil or other contaminants to the process gas. However, a reciprocating compressor requires oil lubricant for the piston rings. This oil eventually ends up in the process gas or it has to be separated to protect the gas turbine. Due to physical contact between the piston rings and the cylinder, the wear of the rings and packing causes particle contamination of the fuel gas. Hence, this contamination could cause premature wear on the turbine blades and other turbine fuel gas passages
Which is best Rotary compressor or reciprocating compressor?
Receip or Piston type compressor are used for large duty cycle work (A/c or other equipments), energy hungry but last longer (Heavy Duty). Where as rotary compressor are energy efficient with higher ( Energy Efficiency Ratio) but lower duty cycle and shorter life. Selection of compressor are based on the nature of application. Normally, for room A/Cs with capacity less than 3 ton, most companies offer rotary compressor due to it's EER and less duty cycle. For heavy duty A/Cs, recip or piston compressor best suited.
What happens when you have a bad air conditioner compressor?
A Typical Air Compressor used in an air conditioning system is used to compress the vapor refrigerant to a higher pressure. If your compressor is not good enough to compress to the required pressure then your air con. will not provide a good cooling effect. P.S. : The temperature when changed on the main panel will directly change the pressure of your compressor which will affect the room temperature.
How will and overcharged condenser run?
An overcharged condensor will run poorly. It will have a higher discharge temperature, high condensor subcooling, higher condensor splits and a high compression ratio.
What is high pressure triplex plunger pump?
Its a mechanical equipment which operates with higher output pressure relatively high temperature. In simplified terms it can defined as, A reciprocating pump with three pistons or plungers
What is the difference in a pump and compressor?
they have different names A Pump is a mechanical device which transfers Liquid from a lower point to a higher point.Eg: Centrifugal pump,Rotary pump,Reciprocating pump. A Compressor is a high pressure mechanical device which basically compressors air/gas Well, a compressor compresses a gas and a pump moves a liquid. Compressors are often used in refrigeration applications where gas is transformed into a liquid and vice-versa, so the main task for the compressor is not to move the gas but to compress it.
Why do the suction pressure increase of a reciprocating compressor?
Pressure increases due to load(or heat intake from evaps).if asking about off cycle. If asking about compression cycle,its the compression of vapor into a higher pressure side of system along with heat of compression adding to temp-pressure relationship.
If you raise your cars air conditioner to a higher temperature will you use less gas than if you keep it cooler?
The gas efficiency of a vehicle is determined by how much power is being used. The air compressor is what affects the gas mileage. The hard the compressor works the more gas a car will use. If the compressor is on the gas economy will go down.
Why is the pressure ratio higher in a centrifugal compressor than an axial compressor?
There is a substantial increase in radius across the rotating blade rows of a centrifugal compressor, which is its primary distinguishing feature from the axial-flow compressors to get higher-pressure ratio. Who says the compression ratio on a centrifugal is higher than that of a screw compressor? Unless I`m not properly understanding the question, these facts are true: a screw (axial) compressor is a positive displacement machine, meaning everything that goes into it will come out. There are no losses for re-expansion etc. A centrifugal compressor`s impeller is designed with a given amount of `lift` which is basically the difference between suction and discharge pressures or compression ratio. Exceeding the designed lift capability results in a surge where the gas momentarily goes backwards through the impeller until the excess lift condition is corrected.
Is air conditioner compressor supposed to kick on even while not in use on 1999 ranger?
If the outside temperature is about 50 degrees Fahrenheit ( 10 * C ) or higher and the defrost or floor and defrost modes are selected the air conditioning compressor will cut in and out as it dehumidifies the air ( that's normal )
Why is it that the higher the temperature the higher the sound?
Sound and temperature are not connected.
