- Hi, pleass help me solve this problem. I need it asap. Thank you so much. *** A thermometer in a 10 x 8 x 4 m room reads 25°C and a humidistat reads the R. H. to be 33%. What mas of water vapor is in the room? Saturated air at 25°C contains 19.33 g h2O/m^3.Air enters a humidifier at 20.25 C and 30% RH. The air is at a constant pressure of 101.325 kPa. If the air leaves the humidifier at 80% RH, what is: The exit dry-bulb temperature of the air in C The saturation effectiveness in % of the humidifier1-What is fog? Show on the psychrometric chart when two air streams yield fogged state of air? 2-Show the following processes on the skeleton psychrometric chart: (a) Dehumidification of moist air by cooling; and (b) Adiabatic mixing of two air streams? 3-With the help of psychrometric chart, explain the following processes: 1. Sensible heating and sensible cooling process; 2. Heating and dehumidification process : 3. Cooling and humidification process; and 4. Cooling and dehumidification process? 4- Prove that the partial pressure of water vapour in the atmospheric air remains constant as long as the specific humidity remains constant? 5-An unsaturated air stream is undergoing adiabatic saturation process and the outgoing air is saturated. Draw the system schematically. Represent the process on T-s and psychrometric charts. Find, for the incoming stream of air, humidity ratio from the adiabatic saturation equation obtained from heat balance? 6-Prove that the enthalpy of the…
- Pls. Answer thank you! An air conditioned theater is to be maintained at 80°F dry bulb temperature and 50% RH(h = 31.35 Btu/lb). The calculated total sensible heat load in the theater is 620,000 Btu/hr, and the latent heat load is 210,000 Btu/hr. The air mixture at 84oF db and 72°F wb temperature(h = 35.82 Btu/lb) is cooled to 63°F dry bulb and 59°F wet bulb temperature (h = 25.78 Btu/lb)by chilled water cooling coils and delivered as supply air to the theater. Calculate the tons of refrigeration required.! Required information Problem 14.095 - Evaporative Swamp Cooler NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air enters an evaporative cooler at 1 atm, 40°C, and 20 percent relative humidity at a rate of 7 m³/min, and it leaves with a relative humidity of 90 percent. Use data from the psychrometric chart. 1 atm 40°C 20% Air Water mw K K Humidifier √2=90% Problem 14.095.b - Evaporative Swamp Cooler Determine the required rate of water supply to the evaporative cooler. The required rate of water supply to the evaporative cooler is kg/min.Q# 2: Chapter 14: Gas vapor mixtures and air-Conditioning (Psychrometric chart) doly to design air conditioning systems using the psychrometric chart, and mass and energy balance relations CLO 4 Air enters an air-conditioning system at 20C and 70 percent relative humidity at a rate of 2 m' /min It is cooled to 15 °C and saturated when the liquid water leaves the system at 32°C. Calculate the amount of water removed from the air and the rate of heat removal from the air.

Determine the dry bulb temperature of the mixed stream.A. 74.7 °FB. 85.7 °FC. 98.4 °FD. 107.5 °FPls. answer this ..Thank you! Two airstreams are mixed steadily and adiabatically. The first stream enters at 37 C and 32 percent relative humidity at a rate of 16 m3 /min, while the second stream enters at 13 C and 92 percent relative humidity at a rate of 25 m3 /min. Assuming that the mixing process occurs at a pressure of 1 atm, determine the specific humidity, the relative humidity, the dry-bulb temperature, and the volume flow rate of the mixture.Using a psychometric diagram, describe the heating and humidification process from the following data. Initially the air was at dry bulb temperature (DBT) 35 ° C and RH 35%. air preheated to DBT 85 ° C. The heated air is then flowed through a humidifier to increase the RH to 25%. for this process, count, a. change in absolute humidity of air from initial to final conditions = ..... (kg water / kg air) b. change in air enthalpy from initial to final conditions = ..... (kj / kg air)
