c. Kapasitas kelembaban tanah (soil moisture capacity).
The objective of the study is to determine besarnya keandalan debit inflow andalan waduk wonogiri dan menemukan pola operasi waduk wonogiri. This study also aims to determine the water demand and water supply in the area. The results showed that the inflow was able to meet the water demands for the current time and in the future.
Air Temperature
Air temperature is a key weather parameter that affects many aspects of our lives. It has come a long way since the development of the first thermometer and now we have a variety of instruments that can measure it in real-time.
Air consists of gas molecules that are constantly moving this way and that at very high speeds. They are in constant collision with each other and with solid surfaces. The more energy the molecules have, the higher the air temperature will be.
The temperature of the air varies from place to place. This is due to many factors such as altitude, solar radiation and humidity. It also depends on the movement of vast pools of air called air masses. The temperature of the air will be different at a given point if it is near a warm or cold mass. For example, it will be warmer at a mountain or colder at the ocean.
Air Pressure
Air pressure is the force per unit area exerted by a column of air above an object. It is a cumulative effect of many molecules Andalan69 constantly colliding with the object’s surface. Air pressure is measured in units called inches of mercury (Hg) and millibars. Meteorologists usually refer to it as barometric pressure.
The air pressure varies from day to day at the Earth’s surface. This is because the atmospheric temperature varies, with warmer air being less dense. The pressure is highest at sea level. The pressure decreases as you rise in altitude. This is why your ears “pop” when you climb into a plane, as the airplane ascends into thinner air.
In warm air, the gas molecules are closer together and have a higher velocity than in cooler air. Therefore they exert a greater force on the surface of an object. The same effect causes air pressure to increase when you fill a tire with air, as the molecules have more collisions with the sidewall of the tire.
Air Humidity
Humidity is the concentration of water vapor in the air. Although invisible to the eye, water vapor is a very important part of the atmosphere and is responsible for weather phenomena such as dew and fog. Humidity is also an indicator of the likelihood for precipitation. Humidity can be measured in two ways: RELATIVE humidity (%) and SPECIFIC humidity (g of moisture per cubic meter of air).
Air that is too humid makes it difficult for your body to regulate its temperature because the water vapor that rises into the air cannot evaporate as quickly as other gases, such as nitrogen or oxygen. This can lead to sweltering heat, especially in combination with high temperatures.
Air that is too dry can also be a problem because it reduces air circulation and traps pollutants in the air. This can make breathing more difficult for people with allergies and asthma. It can also create a breeding ground for mold and mildew, which can cause damage to your home and possessions.
Air Velocity
Air velocity, its mean value and turbulence intensity influences our perception of indoor thermal comfort. The speed of the flow of air in a room can be affected by movement of people in the space, temperature differences and ventilation flows.
Air is a gas made up of diatomic molecules (nitrogen and oxygen) that move around at random and collide with each other and the surfaces of objects like walls. During this process they transfer energy to each other and to the materials they pass through such as ductwork.
Air velocity is usually measured using an airflow meter such as a vane, cup or hot wire type. It is important for understanding and controlling ventilation systems, aerodynamics testing, fume hood verification and other situations where the movement of air is a primary concern. The higher the velocity the greater the rate of heat exchange with the adult. This can affect thermal comfort and draught performance. In some cases it can also impact the diffusion of VOCs such as formaldehyde.
