Which one has high vapour pressure water or alcohol?
alcohol has high vapour pressure than water at room temperature.
What is difference between cavitation and supercavitation?
CAVITATION is the process of formation of vapour bubbles of flowing fluid in a region where the pressure of the liquid falls below its vapour pressure and the sudden collapsing of these vapour bubbles in region of high pressure. where SUPERCAVITATION IS THE CONTROLLED FORM OF CAVITATION WHICH HELP US TO attain more underwater speed
Why does the vapour pressure of water contribute to the total pressure in the bottle?
by equalizing water levels you can assume that the gas you isolated in the chamber is at atmospheric pressure
What is the pressure in domestic LPG cylinder?
Pressure in an LPG cylinder is dependant of the ambient temperature and the LPG mix considered. For 70% Propane and 30% Butane at 20 degrees Celsius the pressure is 102 PSI (lb/sq.in.) or 703 KPa. Please be aware that the pressure inside an LPG vessel will not drop as vapour LPG is being used. LPG cylinder is not to be understood and dealt with as a pressurised gas storage cylinder that will drop in pressure if gas is being taken out of the cylinder. LPG cylinder contains both liquid and vapour, as vapour is being used at an appliance the liquid vaporises under natural conditions and generates more vapour, hence the efficiency of the LPG storage systems.
What do you mean by condenser airside pressure drop?
when water vapour condenses and forms clouds whichthen produces an air pressure which produces precipitation like a water cycle.
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
How do you calculate suction pressure for air theoretically?
Air has a pressure, but not a suction pressure. Air pressure is measured with a barometer, you do not calculate it. Suction pressure is a concept which applies to a pump. Suction pressure = static pressure + surface pressure - vapour pressure - friction pressure.
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.
How can you calculate the vapour pressure of water over the solution at 90 degrees Celsius vapour pressure of water at 90 degrees Celsius is 525.8mmHg?
If this solution is a mixture you would use Henry's or Raoult's Law. If this is pure water then the answer is already in the question.
How do you calculate the efficiency of vapour absorption machine?
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
Does the evaporation in the evaporation column influence the total pressure?
evaporation as such influence on the total pressure. evaporation occurs when the total pressure is greater than the surface molecules vapour pressure. as the rate of evaporation increases , more vapour will be there at the top, and then the new total pressure will become the sum of the earlier total pressure and vapour pressure of the vapour evaporated. hence total pressure increases.............
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
Which one has high vapour pressure water or alcohol?
alcohol has high vapour pressure than water at room temperature.
Why the relative lowering of vapour pressure is independent of temperature?
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.

Does vapour pressure include the partial pressure of water vapour in the atmosphere during boiling process?
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
What is the condition which occurs when the atmospheric pressure is equal to the vapour pressure?
boiling
