how to calculate the vapour absorption mechine efficiency and per TR steam consumption
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 mechine
An absorber is a device which allows gas or vapour to be absorbed by a liquid, a person who absorbs, or a material which absorbs neutrons in a reactor.
In a gross sense, the water vapour in clouds is has the greatest effect.
In the automobiles, in the fuel system,sometimes large amount of vapour formation takes place at higher temperature.The cause is evaporation of some of the more volatile components of the petrol. Bubbles of vapour from in the fuel system can prevent the easy flow of fuel. This is called vapour lock.
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
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......
do u mean air cycle machine (acm) system or vapour cycle system
Gaseous exchange and evaporation of water vapour
Relative lowering of vapour pressure is function of pressure of pure liquid and pressure of solutions when you increase temperature both the values increase and compensate the increase value, According to the Raoult's law, Psolvent = Xsolvent Po where Psolvent is the vapour pressure of the liquid solution, Xsolvent is its mole fraction in the solution and Po is the pure vapour pressure.
