Why coefficient of performance of absorption cycle is less than compression cycle?
In case of vapour compression cycle (VCC) the COP is given by (desired effect / work input). in the other words it can be defines as what we want and what we are paying for that... so in VCC the paying amount is very less as due to low temperature difference that why its value is more than 1. but in case of vapour absorption system the COP is given by (heat taken by evaporator/ heat given to generator). the heat input taken by evaporator is less as compared to heat given to generator.. that why its COP is less than 1......
What is vapour liquid equilibrium data?
when number of molecules into vapour state from liquid state is equal to number of molecules going from vapour to liquid equilibrium is said to have been established
What is a working principle of mercury vapour lamp in 4 to 5 lines?
Mercury vapour contained in an evacuated glass bulb.Vapour warmed.High voltage applied to electrodes inside lamp.Vapour conducts and allows current flow, excitation causes vapour to glow brightly.Little or no resistance, so requires a ballast in line.
Unit of water vapour diffusion resistance factor?
unitless
How do engineers use the quandratic formula?
Law of motion is quadratic equation and is use in calculate of object trajectory. Fluid dynamic for sizing of pump is also second order equation. Quadratic equation or higher may use to fit equation for fast calculation of result. Example on vapour density equation for the use of evaporative mass transfer. We do need to know how much water air can take. It could use the data from table but the work will be lengthly. We can make data in the table a form of polynomial equation and so put it into program for calculated out this require vapour density.
What is Vapour absorption machine?
It is a refrigeration unit based on Vapour Absorption Refrigeration Cycle (typically refrigerants used are Water or Ammonia).
What happens if vacuum is 10 mm Hg in Vapour absorption machine?
what happens if vacuum is 10 mm hg in vapour absorption mechine
What is the function of absorber in the vapour absorption system.?
in orde to reduce the pressure........cming from the evaporator
What is the function of absorber in vapour absorption refrigeration system?
in orde to reduce the pressure........cming from the evaporator
How do you calculate actual vapour pressure?
pressure=force/area
Is it possible to design a machine that has an efficiency that is greater than 100 percent?
An ordinary domestic heat pump appears to have an efficiency of up to 300% or so. That is it will deliver 3kw of heat for each 1kw of electricity it consumes. But that is illusory because it extracts the extra heat from the water vapour in the air. So in real life, the laws of physics win out.
Which gas molecules if any are primarily responsible for the absorption of visible light?
In a gross sense, the water vapour in clouds is has the greatest effect.
Ethylene glycol has a vapour pressure of 14.9mmHg at 373K and a vapour pressure of 49.1 mmHg at 398K calculate the enthalpy of vapourization of ethylene glycol?
59.0 KJ/mol
What are examples of atomic absorption spectroscopy?
When white light from mercury vapour lamp is passed through sodium vapour then we have as outcome a continuous spectrum of colours with two black lines in the yellow-orange region. These two lines stand for the absorption of 5890 A and 5896 A lines of sodium atom Another example is Fraunhofer lines seen in the continuous spectrum got from sun. These lines are due to absorption of characteristic frequencies of metals present in the chromosphere of the sun
Why did you need to calculate leaf surface area in tabulating your results?
transpiration is the loss of water vapour from the leaves of the plant, therefore the bigger the surface area of the leaf, the more water vapour lost from the plant.
How does the airplane airconditioning system works?
do u mean air cycle machine (acm) system or vapour cycle system
How do you calculate vapour pressure from an EOS?
Use the Equation of State (EOS) in combination with the Antoine's Equation to determine vapor pressure.
