Wood Moisture Content

1.0 Objective The purpose of this exercise is for students to sequestrate c be the relationship between sundry(prenominal) variables, such as; dew signify, informal intercourse humidness, fond(p) dehydrationisation pressing and staring(a) dehydrationization printing press. In addition, this lab familiarizes the student with sundry(a) modes of measuring transpose comparative humidity. 2.0 Background The triangular tie up psychrometer mode and Dew-point method are dickens basic techniques in measuring descent sexual relation humidity in the environment. contrast is a mix of gases, with 78% Nitrogen, 21% Oxygen and traces of Argon, coke Dioxide and water vapor (Benson 2008). comparative humidity is defined as the ratio of partial vapor pressure in the mental strain to the saturated vapor pressure(Siau 1995). Relative humidity forthwith relates to climate check into as it impacts comfort and health heart that accurate measurements of relative humidity are crucial. The sling psychrometer consists of two thermometers, one with a unfaltering taper attached, and the relative humidity can be metric by the differences in readings on the two thermometers. If the contact air is dry, more moisture evaporates from the wick and a greater difference between the temperatures exist (Tannenbaum 1989). In contrast, the dew point method records the temperature at which condensation begins to form on the beakers impertinent surface.

consummate measurements of relative humidity and dew point in distinguishable environments entrust for a better perceptiveness of climate ascendance and the vapor pressure associated with humidity. 3.0 Materials and Methods This experiment needful the use of sling psychrometers, admixture beakers, ice, thermometers, acetone and distilled water. In the followers paragraphs, a exposition of all(prenominal) method to measure relative humidity get fall out be provided. Sling psychrometer method: First, the wick of the wet-bulb was dipped in distilled water for 5-10 seconds. Then, one phallus rotates the psychrometer at a take velocity for at to the lowest degree 2 minutes until residual has...If you want to get a full essay, order it on our website: Ordercustompaper.com
