Calculate the mass of water vapor present in a room of 520m ^ 3 volume containing air at 27C on a day where the relative humidity was 55% (vapor pressure at 27C = 26.74Torr)
2. Calculate the mass of water vapor present in a 520 m3 volume room containing air at 27 ºC on a day where the relative humidity was 55%. (Vapor pressure at 27 ºC = 26.74 Torr) 3.Given that the air density at 0.987 bar and 27 ºC is 1,146 kg / m3, calculate the total moles of air and the total mass of the air found in 400 m 3. Also determine the molar fraction and the partial pressure of...
please provide me with the solutions as fast as possible A gas mixture with id entical mass fractions for each component will have the identical mole fractions 1. T F as well. T F 2. The sum of the mass fractions for a real-gas mixture is equal to 1 The molar mass of Methane is 0.5182 kg/kmol. 3. A real-gas mixture has a compressibility factor of 0.49. Using the ideal gas relationship, 4. the volume of the mixture b. Underestimates...
a. Calculate the dry air and water vapor mass flow rates (lb/min) if the volume flow rate is 1,000 cfm, the humidity ratio is 0.025 lbv/lba, and the dry air density is 0.072 Iba/ft3. b. Assume the above air enters an evaporator coil at 90°F where it is cooled in a constant humidity ratio process until reaching the 100 % RH curve ( the temperature at that point is the dew point. The air then keeps dropping in temperature, following...
15. The relative humidity of air equals the ratio of the partial pressure of water in the air to the equilibrium vapor pressure of water at the same temperature times 100%. If the relative humidity of the air is 56% and its temperature is 70°F, how many grams of water are present in a room measuring 15 ft x 10 ft x 11 ft? The vapor pressure of water at 68 °F is 17.54 torr. Show your work 15. The...
0.75 L bottle is cleaned, dried, and closed in a room where the air is 24°C and 38% relative humidity (that is, the water vapor in the air is 0.38 of the equilibrium vapor pressure at 24°C). The bottle is brought outside and stored at 0.0°C. (a) What mass of water condenses inside the bottle? (b) Would water condense at 10°C?
The relative humidity of air equals the ratio of the partial pressure of water in the air to the equilibrium vapor pressure of water at the same temperature times 100%. If the relative humidity of the air is 58% and its temperature is 68 oF , how many moles of water are present in a room measuring 12 ft x 10 ft x 8 ft? The vapor pressure of water at 68 oF is 17.54 torr.
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...
A student leaving campus for spring break wants to make sure the air in her dorm room has a high water vapor pressure so that her plants are comfortable. The dorm room measures 3.38 m x 4.61 m x 3.47 m and the student places a pan containing 1.59 L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when she closes the door, and that the temperature remains...
Given this data: Volume = 425.5 m^3 Pressure = 10.17 Pa Temp = 294.8 K Relative Humidity = 47.8% a.) What is the mass of the air in the room? b.) What is the weight of the air in the room?
