Lab Instructions: EX: 21-22 Adiabatic Processes: Humidity- the amount of water vapor present in the air. Absolute Humidity- The amount of water vapor present in a unit volume of air. Relative Humidity-the ration of the amount of water vapor actually present in the air to the greatest amount possible at the same temperature. R. H = Actual Water Vapor content/ Water Vapor Capacity (Maximum Capacity that the air can hold) Saturation Mixing Ratio- The water vapor capacity of air at given temperature

Date_________ Laboratory _________ Title FLAT BOTTOM CLOUDS (PART 1) Introduction You have probably heard people say hot air rises‚ after all isnt that why hot air balloons rise Well‚ if this were the case shouldnt we be sun bathing instead of skiing on the mountaintops What happened to all that hot air There must be more to this story. In this laboratory you will be investigating how pressure affects the temperature of air and how this relates to the formation of clouds in the troposphere

example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional area of the tower outlet of air was found to be 0.005 m^2. With the values from the psychrometric chart and cross-sectional area‚ the mass flow rates of the dry air and moist air were calculated‚ as shown below for Trial 1

However‚for the linked answer question pair‚ where each question carries 2 marks‚ 2/3 mark will bededucted for a wrong answer to the first question only. There is no negative marking for wronganswer to the second question of the linked answer question pair. If the first question in thelinked pair is wrongly

Define human error‚ and explain the HFACS method used to classify human error and how HFACS can be both reactive and proactive. Remember‚ you must have a title page‚ 300 word body written in 3rd person‚ and at least two references. the temperature remains constant and moisture is added by evaporation‚ the absolute humidity(volume of water per volume of air) will increase‚ the relative humidity (percentage of saturation achieved) will also increase and the dew point temperature will also increase

Evaporation and Transpiration Evaporation and transpiration (evapotranspiration) are components of hydrologic cycle‚ which at principle‚ can be calculated from meteorological observations such as temperature‚ humidity‚ radiation‚ wind speed‚ etc. The process‚ however‚ is quite complex and a substantial literature has been produced on it. In this chapter our focus is mainly on the concept and simple estimations of evaporation and transpiration. Mechanism of evaporation from water surfaces Here
