- If the absolute amount of water vapor in air at 25 oC is 2500 Pa and 3000 Pa at 30 oC, which one has the highest relative % humidity?
Homework Answers
Relative humidity is defined with respect to vapour pressure of pure liquid at a given temperature,
Higher the vapour pressure of water in the atmosphere, higher will be the relative humidity,
At 30°C , more amount of water vapour is present, hence at this temperature, relative humidity will be higher.

Humidity is the amount of water vapor in the air at a given time
Humidity is the amount of water vapor in the air at a given time. At warm temperatures, air can hold more moisture than it can at cold temperatures. Relative humidity is the amount of vapor the air is holding expressed as a percentage of the amount the air is capable of holding. For example, at 86 degrees Fahrenheit, air can hold a maximum of 30.4 grams of water per cubic meter. If the air at the same temperature is holding...

1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...

Suppose: the dewpoint temperature is 25 degrees Celsius; the water vapor capacity is 30 grams per cubic meter; the actual absolute humidity is 15 grams per cubic meter. What is the relative humidity?
We are learning about relative humidity. 1st part- what is the water vapor content at 25 degree C air if its relative humidity is 50%? 50=10/20 x 100% gives me the water vapor content of 10g/kg. 2nd p...
We are learning about relative humidity. 1st part- what is the water vapor content at 25 degree C air if its relative humidity is 50%? 50=10/20 x 100% gives me the water vapor content of 10g/kg. 2nd part- If the air was at 25 degree C at sea level, and rises to 1,000 meters, then what will its temperature be? It will drop by 10 degree C, so the temperature will be 15 degrees C. At 15 degree's C the...

11.65 Steam as water vapor at 100 kPa, 120°C comes out from a pipe into the atmosphere. Assume it mixes adiabatically with the ambient air at 100 kPa, 20°C, 45% relative humidity so the final mixture has an absolute humidity of ? = 0.01. Find the final mixture temperature and relative humidity

(a) What is the vapor pressure of water at 20.0◦C? (b) What percentage of atmospheric pressure does this correspond to? (c) What percent of 20.0◦C air is water vapor if it has 100% relative humidity? (The density of dry air at 20.0◦C is 1.20 kg/m3). I got that the vapor pressure of the water will be 2.33x103 Pa, but I am getting hung up on the formula for part b, which is where I can really use the extra help...

1. A building air-condition unit is designed to cool 2500 ft3/min of outside air (95°F, 740 mmHG, 82% relative humidity) to 50°F, thereby condensing a portion of the water vapor. The system then heats the air and sends it to a building at 68°F a) Calculate the rate of water condensation. b) Calculate the volumetric flow rate of air delivered to the building.
