psia=psig+atmospheric pressure where, atmospheric pressure = 14.7psi therefore psig=psia-atmospheric pressure psig=100-14.7 psig=85.3psig
7 F
100-140 psig
Evaporation occur at any temperature.Boiling occur at 100 oC.
Adjust the temperature. This is very fidgety if you want evaporation to occur at a particular rate. But try lowering the temperature back towards the boiling point (for a liquid is 100 degrees celcius) but not below because the evaporation process will stop.
Your high and low pressure readings will be directly affected by the ambient air temperature and humidity. At 60 degrees (Fahrenheit), you should be looking right about at 58 psig. At 100 (Fahrenheit), you'd be looking at something closer to 125 psig.
If the wet bulb temperature is the same as the dry bulb temperature, it means that the air is saturated with moisture and the relative humidity is at 100%. This indicates that the air is at the dew point temperature, and condensation may occur.
No, water can evaporate at any temperature, not just at 100 degrees. Evaporation occurs when water molecules gain enough energy to break free from the surface of the liquid and enter the air as vapor.
- Separation by distillation: at 100 deg. C - Separation by evaporation: at any temperature above 0 deg. C.
Evaporation can occur at any temperature, but it generally happens faster at higher temperatures. Warmer temperatures provide more energy for water molecules to escape into the air as vapor.
heat whatever you are evaporating to a temperature above its boiling point. for water you must heat it to 100 degrees C
Evaporation occur at any temperature, boiling only at the boiling point - 100 oC at standard pressure.
