The specific volume lines are obliquely inclined.ġ0. Enthalpy lines and specific volume lines are the same.Ĭlarification: Though both of the lines representing given properties are inclined straight lines and uniformly spaced, but the slope of both the lines are different. So, on the saturation curve, for every dry bulb temperature, the value of relative humidity remains 100%.ĩ.

Relative humidity on saturation curve has value of _% at various dry bulb temperatures.Ĭlarification: Relative humidity is the ratio of actual mass of water vapor in the given volume of moist air to the mass of water vapor in the same amount of saturated air. Hence, these lines are also known as moisture content lines.Ĩ. So, specific humidity denotes moisture content. Specific humidity lines are also known as_Ĭlarification: Specific humidity is the moisture present in the air mixture. The obliquely inclined lines from the saturation curve and on the dry-bulb temperature lines denote Specific volume.ħ. What is represented by obliquely inclined straight lines but uniformly spaced on the psychrometric chart?Ĭlarification: The psychrometric chart has DBT on the x-axis and specific humidity on the y-axis. The inclined lines from the saturation curve and parallel to the wet-bulb temperature lines denote Enthalpy.Ħ. What is represented by inclined straight lines but uniformly spaced on the psychrometric chart?Ĭlarification: The psychrometric chart has DBT on the x-axis and specific humidity on the y-axis. The horizontal lines from the saturation curve and parallel to the abscissa denote dew point temperature.ĥ. What is represented by horizontal lines but non-uniformly spaced on the psychrometric chart?Ĭlarification: The psychrometric chart has DBT on the x-axis and specific humidity on the y-axis. The inclined lines from the saturation curve and on the x-axis denote wet-bulb temperature.Ĥ. What is represented by inclined straight lines but non-uniformly spaced on the psychrometric chart?Ĭlarification: The psychrometric chart has DBT on the x-axis and specific humidity on the y-axis. From 0 to 100 %, these lines are drawn at an interval of 10%.ģ. The curved line on the grid shows the relative humidity. Which of the following is represented by curved lines on the psychrometric chart?Ĭlarification: The psychrometric chart has DBT on the x-axis and specific humidity on the y-axis. So, the vertical and uniformly spaced lines denote dry bulb temperature and spaced by 5☌.Ģ. What do vertical and uniformly spaced lines indicate on the psychrometric chart?Ĭlarification: The psychrometric chart has DBT on the x-axis.
