10 Questions
In a steady state, the heat flow from air to wick is less than the latent heat of vaporization required to evaporate the moisture from the wick.
False
The wet bulb temperature is indicated by a dry bulb thermometer or similarly modified temperature sensor.
False
The equation relating partial pressures and temperatures of air-vapor mixtures is widely used in calculations to determine thermodynamic properties.
True
The dry bulb temperature is always higher than the wet bulb temperature.
True
The vapor pressure at 40°C is 4.246 kPa.
False
The dew-point temperature is the same as the wet bulb temperature.
False
The humidity ratio is the ratio of the mass of water vapor to the mass of dry air.
True
The humid volume is calculated using the ideal gas law.
True
The relative humidity is the ratio of the partial pressure of water vapor to the vapor pressure at the dry bulb temperature.
True
The gas constant used in the ideal gas law is 8.314 J/mol·K.
