why does vmc decrease with altitude?
156180
Vmc will decrease with altitude in a normally aspirated engine due to the fact that the engine is producing less thrust. Therefore, your control surfaces, at a given speed, will be better able to counteract the yaw tendancy due to a failed engine.... when the remaining engine is producing less power.

Absolute humidity is the total measure of water in the atmosphere (not percentage of saturation). As you get higher in altitude, the atmosphere becomes thinner (less pressure). This means that the total amount of water vapor the atmosphere can potentially hold is decreased.

There are 4 fundamental causes for a drop in SvO2: The cardiac output is not high enough to meet tissue oxygen needs. The Hb is too low. The SaO2 is too low. Oxygen consumption has increased without an increase in oxgyen delivery.

The troposphere contains almost all the water vapor and most of the dust. This layer subject to intense mixing due to both horizontal and vertical mixing. Temperature decreases with height at an average rate of 10C per 167m of height above sea level. This calls the normal lapse rate.

Pressure varies with altitude, with denser air residing in lower altitudes and lighter air in higher altitudes. This is caused by the Earth's gravity—its strength decreases the farther away from the center of the planet, therefore it holds fewer molecules together in the same amount of space.

As we go up or our altitude increases, temperature falls. The rate of decrease of temperature is 6.5 degrees C for each 1 km altitude change. This can also be written as 3.6 degree F for every 1000 ft increase in altitude.

Most recipes are designed to be prepared at low altitudes. ... called for in the recipe. High-altitude recipes use less baking powder than is needed at sea level, as the decreased air pressure causes gases in foods to expand faster. Baking powder is 20 percent more effective at 5,000 feet than it is at sea level.

VSO. — Stall speed in landing configuration. Lower limit of white arc.

Because the VGTs have moving vanes that adjust their size based on the amount of air needed, they're able to directly control this air-to-fuel ratio at low and high RPMs. This maximizes your boost for a much greater range.

Keep in mind that wearing an altitude mask might cause you to hyperventilate or even faint, due to its restrictive breathing. People who have high blood pressure or other cardiovascular problems should avoid using training masks.

So, usually, as the altitude or elevation increases, the weather gets colder and in fact the climate becomes naturally harsher with more intense weathering such as windier and colder. Furthermore, there is also less air as the altitude or elevation increases.

Under normal atmospheric conditions, as altitude increases, air temperature drops between 1°C and 3°C for every 1,000ft (300m) height gained. For dry air the temperature drop is higher, saturated air the drop is more likely to be 1°C. ... A good rule of thumb is to assume 2°C temperature drop per 1,000ft (300m).

Air Pressure and Humidity. ... Air pressure changes with altitude. When you move to a higher place, say a tall mountain, air pressure decreases because there are fewer air molecules as you move higher in the sky. Relative humidity is the amount of moisture the air can hold before it rains.

Because air pressure decreases at the rate of 0.91 inches per 1,000 feet of ascent, rising air expands and cools. The flat bottom of cumulus clouds defines the exact height at which a critical combination of temperature and air pressure causes water vapor within the rising current to condense into a visible cloud.

The Brainliest Answer! As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.
375773
As you increase altitude, the air gets increasingly rarer, which leads to a loss of pressure. Temperature is directly proportional to pressure, so the lower the pressure, the lower the temperature. In short, the higher the altitude, the lower the temperature.

The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude.
