Moist air undergoes a heating and humidification process at a pressure of 101.325 kPa from an initial state of 15°C db and 80% relative humidity to a final state at 22ºC and 60% relative humidity. If the mass flow rate of the air at the initial state is 27.7 kg da/s, what is the increase in the water content of the air? Express your answer in kg/s. In your written solution, draw the process in the psychrometric chart, show the initial and final state and the values obtained from the chart.
If the mass flow rate of the air at the initial state is 27.7 kg da/s , then the increase in the water content of the air is -0.039648 kg/s.
How to find?The process can be drawn on a psychrometric chart as shown below:
In order to solve the problem, the following steps are to be followed:
Step 1: Find the Humidity Ratio at state 1
The Humidity Ratio (ω1) can be found using the formula:
\(Relative Humidity (RH1) = (ω1/ωsat) × 100\)
Where,
ω1 = Humidity Ratio at State 1
ωsat = Saturation Humidity Ratio at State 1
The value of saturation humidity ratio (ωsat) can be obtained from the psychrometric chart.
ωsat at State 1 corresponds to temperature T1 and 100% relative humidity.
From the chart,ωsat = 0.012 kg water/kg dry air.
Therefore,
RH1 = (ω1/ωsat) × 100
80% = (ω1/0.012) × 100ω1
= (80/100) × 0.012
= 0.0096 kg water/kg dry air.
Step 2: Find the Humidity Ratio at state 2The Humidity Ratio (ω2) can be found using the formula:
RH2 = (ω2/ωsat2) × 100
From the chart,ωsat2 = 0.0136 kg water/kg dry air.
Therefore,
RH2 = (ω2/ωsat2) × 10060%
= (ω2/0.0136) × 100ω2
= (60/100) × 0.0136
= 0.00816 kg water/kg dry air.
Step 3: Find the increase in Humidity Ratio
Increase in Humidity Ratio \((Δω) = ω2 - ω1Δω\)
= 0.00816 - 0.0096
= -0.00144 kg water/kg dry air.
The negative sign indicates that there is a decrease in the water content of the air.
Step 4: Find the Mass flow rate of water
Mass flow rate of water can be found using the formula:
Mass flow rate of water = Mass flow rate of dry air x ΔωMass flow rate of water
= 27.7 x (-0.00144)
= -0.039648 kg/s.
Therefore, the increase in the water content of the air is -0.039648 kg/s.

Answer:
How did the Industrial Revolution affect migration?
The Industrial Revolution had a prodigious impact on migration from 1750-1900. -Industrialization: New innovations were seen throughout this time period, and factories began sprouting across all of Europe. Factories centralized the production of food and common goods resulting in increased migration to cities.
What is the relationship between industrialization immigration and urbanization?
One important result of industrialization and immigration was the growth of cities, a process known as urbanization. Commonly, factories were located near urban areas. These businesses attracted immigrants and people moving from rural areas who were looking for employment. Cities grew at a rapid rate as a result.
Did ethnic enclaves have a positive or negative impact on immigrants in the late 1800s provide evidence to support your response?
The late 1800s saw an enormous influx of immigrants who came to the United States hoping to find better opportunities. Ethnic enclaves had a positive impact on immigrants as it allowed them to have a sense of community in their new country. It also helped them keep their culture and identity alive.
Why does Canada attract immigrants?
With a strong economy providing numerous opportunities and a culturally diverse population, many foreign-born citizens have reaped the rewards of immigrating to Canada. Its educational system makes it attractive to immigrants, and has laid the foundation for future innovation and progress for all of Canada.

Answer:
Planet A orbits faster than planet B.
Explanation:
The first option is not correct because the planet that is further away from the star orbits slower.
The second option is not correct because by having a much longer path to pass and also experiencing lesser gravitational pull, planet B is not having a shorter orbit.
The third option is correct because planet A is closer, thus has a smaller path to pass around the star, and the gravitational pull it expeiences is greater, so it orbits faster around the star.
The fourth option is not correct because the difference in distance from the star, as well as the length of the orbital path, don't allow the two planets to have equal orbital period.

c. Explain what the result of your proof tells you about angles a and b. Specifically, if you
measured one angle, what would you know about the other? (2 points)
The result of the proof shows that the sum of the angles will be 180°.
What is the proof?In the question, we are told that angle a and b are a linear pair and this means that they are angles on straight lines. An angle on a straight line is 180°.
So, this means that if we find one angle, the other can be easily found by subtracting the known angle from 180°. Thus we can prove that the angles are supplementary by virtue of their sums. Let us say that one of the angles measures 90°, we can find the other by simply subtracting 90° from 180° to have 90°.

from earth, the sun and moon have about the same angular diameter.T/F
False. The Sun and the Moon do not have the same angular diameter when observed from Earth.
The statement is false. The Sun and the Moon have significantly different angular diameters when observed from Earth. The angular diameter refers to the apparent size of an object as seen from a particular vantage point. The Sun has an average angular diameter of about 0.5 degrees, while the Moon has an average angular diameter of about 0.5 degrees as well. However, due to the variations in the distances between the Earth, Sun, and Moon, their angular diameters can vary. At times, the Moon appears larger than the Sun during a solar eclipse, while in other instances, the Sun appears larger during a solar transit. Thus, the Sun and the Moon do not have the same angular diameter when viewed from Earth.

why could it be a disaster for an ecosystem if deers eats lions
it's a disaster
Explanation:
because lions keep the deer population under control and if there are slot of deers then the deeper population would be over crowded and since there are many deers they would have to eat more so most of the grass would be gone and other animals wouldn't have a chance to eat
Answer:
Becasue without lions, the herbivores(plant eaters) will overpopulate. Lions reputation of being the 'chief' predator of their habitat as they are known to even kill/eat herbivores such as elephants and giraffes, which are herbivores. The herbivores will eat a lot of the plants and soon there will be no more plants for the herbivores now because the deer ate the lions. The lions subdue that bye eating deer. That is why deer eating lions would be bad for the ecosystem. If you like my answer please give brainliest. If not, then oh well.
Explanation:
given that direct measurements of earth's atmospheric temperature over the last several thousands of years are not available, how can scientists estimate past fluctuations in the temperature?
Scientists can estimate past fluctuations in the temperature by studying indirect evidence such as ice cores, tree rings, and lake and ocean sediments.
Ice cores provide a record of past temperatures and atmospheric conditions, which can be used to calculate changes in the climate over time. Tree rings provide a record of the growth and width of the annual rings, which can be used to infer past temperatures.
Lake and ocean sediments provide a record of past temperatures, as well as other environmental conditions. All of these data can be used to reconstruct past temperatures and other climate variables.
In addition, scientists can use computer models to simulate past climate conditions, helping to further refine the estimates of past temperatures.

what is the serious concern of geography study?
Place is a key topic in geography. Since individuals began to perceive distinctions between locations, geographers have been tasked with figuring out the nature and reasons of aerial differentiation on the earth's surface.
What is the major issue with geographic study?It is focused on people's spatial behaviour, the spatial connections that can be seen between locations on the surface of the earth, and the spatial processes that produce or preserve such connections and behaviours. The points where space (aerial extent) and location converge worry geographers.
Human geographers investigate the spatial dimensions of human behaviour, including where, why, and the outcomes of what people do. Physical geographers describe, simulate, and forecast the patterns of natural phenomena like climate, landforms, soil development, and river movement.
Exploring the connections between the vast variances in cultures, political structures, economics, landscapes, and habitats around the world lets us investigate and understand space and place.
