Question

Use the graph Water Vapor Density Versus Temperature to predict the water vapor density at 100$\%$ humidity for $35^{\circ} \mathrm{C}$

David Collins · Accepted Answer

question Number five in this section is also very similar to the last two questions four and three, where we need to use this graph that is provided in your textbook that shows the water vapor density in units of moles per 1000 liters as a function of temperature in degrees Celsius. This question asks what the 100% humidity value is at 35 degrees Celsius. It doesn&#x27;t ask for units. So I assume that we can use three units that air provided on the graph for water vapor density versus temperature. And if we go to 35 degrees Celsius, where we hit, the graph is the maximum 100%. So this would be the 100% relative humidity, humidity, the maximum amount. And at 35 degrees Celsius, it looks like that we are at about two point to moles of water vapor per 1000 liters

Sherry Tsui · Answer

in this problem. We are roughly given this graph, which is not exactly accurately represented. And we are supposed to use this graph of vapor pressure of water versus temperature to answer four parts of the question. So before this, we can complete this phase diagram. We will have another line here that separates the three phases of liquid solid and vapor in part A. We are asked at what points does water boil at standard atmospheric pressure so the water will boil at point A. Because this is the normal boiling point when the vapor pressure of the substance is equal to standard atmospheric pressure, which is 101.3 k p a. This is where the look would will boil in part B. We are asked at what points is water only in liquid phase. As we can see here in the diagram only point C isn&#x27;t the liquid phase and that will be your answer for C were asked At what point is water Only in the Bieber fees. We can look at the bottom right corner where the vapor phase under that curve and only point D is there. This is where look what is in vapor phase, and at what point is liquid water in the cooler Meriem with water vapor? It is that point B because point B is three triple point, which is defined as where the pressure and temperature where three states of a substance are at equilibrium.

in this question, we have to complete the total water vapor pressure industry conditions off the first item on off the second item. For that, we can use these equation which defines the humidity as a function off the vapor pressure and the saturated vapour pressure we went to calculates the vapour pressure under Mr Conditions. So we solve this equation for the vapour pressure. Then we get the following the vapour pressure P is equals to the humidity, let you call this age finds the saturated vapour pressure. Ask VB divided by 100. And these is the equation we will use to solve this question. Okay, Now we have to look at table 13.3 to get the following data. We want the saturated vapour pressure at 30 degrees Celsius and at five leverage cells use by looking at that table, we get the following and now we are ready to solve the question for the first item. The pressure is equals. True, the humidity, which is 40% times the saturated labour pressure at a 30 degree Celsius which is 4.24 times stand to the toured and this is divided by 100 these results in the vapour pressure off approximately 1.7 time stand to the third Paschal&#x27;s and this is the answer to the first item on the second night. Um, the pressure is given by the humidity 80% times the saturated vapour pressure at five degree Celsius, which is eight 0.72 time stand, the second divided by 100. And these results in the vapour pressure off approximately seven 0.0 times. Stem this second. But skulls that these is down, sir, to the second item.

Mm. So the problem or Chapter 18 problems 69 here and it says, calculate the total water vapor pressure and air on the following two days for a hot summer day, with T equaling 30 degrees Celsius and relative humidity being 0.65 or 65%. Yeah, okay, so from this, we need to figure out what the saturated vapor pressure of water is at 30 degrees. So we look at table 18 to, and we see for 30 degrees. P set is 4 to 40 pascal. And if the relative humidity is 65% you know that P of the paper is 0.65 times 4 to 40 or one or 2000 756 past girls awesome Part B occur this day, says a cold winter day AT T, equaling five degrees Celsius and relative humidity of 0.75 So, again, we need to look at Table 18.2. We should see that a mhm five degrees Celsius corresponds to a saturation saturated vapor pressure of 872 Pascal&#x27;s, so it&#x27;s a little, much smaller pressure, so that means vapor pressure years, then as 0.75 times piece set, or 0.75 times 872 And this comes out to being 654. Pascal&#x27;s awesome.

Charles Thomas · Answer

So we want to calculate the relative humidity. And so I have gone to table 53 and I looked up the vapor pressure of water at 30 degrees. And that&#x27;s the equilibrium value that&#x27;s referred to year. Uh, E. And then I have found a conversion factor for Pascal and tour and, of course, tour or the same Well, one tour is one millimeter. Uh, mercury. And so I&#x27;ve converted the given ah, vapor pressure of water on this particular day in North Carolina. Ah, and converted it to millimeters of mercury. And so this is the vapour pressure that exists. And so the relative humidity is going to be 29.25 voted by 31.82 times 100% you know, to the same on both of those. I don&#x27;t really need him. And I get 91.9 percent humidity

Averell Hause · Answer

So here the percent relative humidity percent relative humidity is defined as the vapor density divided by the saturation vapor density times 100%. And so we can say that, then the vapor density. I would be equal to the relative humidity percent multiplied by the saturation vapor density, and then this would be divided by 100. And so, for a relative humidity of 6% and a saturation vapor density of 51 grams 51.1 grams per cubic meter, we can say that the Baber density would be equaling again. 6% relative humidity 6.0 multiplied by saturation vapor density of 51.1 grams per cubic meter, divided by 100. And we have a vapor density of 3.0 Grant, 3.7 grams per cubic meter. This would be our vapor density. That is the end of the solution. Thank you.
