Whats the best renewable energy source?


The beat renewable energy sources are those sources of energy which can be renewed easily and which is eco-friendly in nature.
Some of the best sources of renewable energy are:
1. Solar energy: The most efficient renewable energy source. The sun rays are absorbed by the solar cells on the solar panel and later it is used as electricity.
2. Wind energy: Used in turbines to make them run and generate electricity.
3. Water energy: Water has been used in hydroelectric plants to produce electricity.
4. Nuclear energy: Nuclear fission is the main source of energy today. The energy generated by this fission is used to produce electricity.

Tips on changing orifice size on AC or heatpump


Tips on changing orifice size on air conditioners and heat pumps.
A smaller orifice will create these changes
1 - Takes more refrigerant charge to get the same superheat
2 - Increases capacity
3 - Decreases Energy Efficiency Ratio
4 - Increases Head pressure
5 - Increases sub cooling
6 - Reduces suction pressure
7 - Increases Watts and Amps

Hello ! I have a Sony DAV-DZ640K Home Theater System, the problem is that I can increase and decrease sound levels for individual speakers, like i am able to increase and decrease surround (back) speakers...


Sound distribution varies according to speaker configuration. You have to select speaker size and placement and a number of other characteristics to get results. A review of the setup instructions in accordance with the physical size of the speakers you are using and nominal impedance values may help.

What are the benefits of undergoing therapeutic massage therapy?


Benefits of massage:
  • Relieves muscle tension by enhancing blood flow, which causes muscles to relax
  • Decreases inflammation by activating genes that naturally reduce swelling
  • Reduces pain intensity by diminishing bodily substances that create and prolong pain
  • Improves recovery by stimulating mitochondria, the "energy packs" driving cellular function and repair

How is latitude related to air temperature


The temperature of the troposphere generally decreases as altitude increases. The rate at which the temperature decreases, dT / dz, is called the lapse rate. The reason for this decrease is as follows. When a parcel of air rises, it expands, because the pressure is lower at higher altitudes. As the air parcel expands, it pushes on the air around it, doing work; but generally it does not gain heat in exchange from its environment, because its thermal conductivity is low (such a process is called adiabatic). Since the parcel does work and gains no heat, it loses energy, and so its temperature decreases. (The reverse, of course, will be true for a sinking parcel of air.) [1]
Since the heat exchanged dQ is related to the entropy change dS by dQ=T dS, the equation governing the temperature as a function of height for a thoroughly mixed atmosphere is
9df09585dbe18cef06221a59290536de.png where S is the entropy. The rate at which temperature decreases with height under such conditions is called the adiabatic lapse rate.
For dry air, which is approximately an ideal gas, we can proceed further. The adiabatic equation for an ideal gas is [3]
beb483b44843aad0a6cddff7b1385c8a.png where γ is the heat capacity ratio (γ=7/5, for air). Combining with the equation for the pressure, one arrives at the dry adiabatic lapse rate,[4]
c4507116c9a4244af81e3aa8b865d863.png If the air contains water vapor, then cooling of the air can cause the water to condense, and the behavior is no longer that of an ideal gas. If the air is at the saturated vapor pressure, then the rate at which temperature drops with height is called the saturated adiabatic lapse rate. More generally, the actual rate at which the temperature drops with altitude is called the environmental lapse rate. In the troposphere, the average environmental lapse rate is a drop of about 6.5 °C for every 1 km (1000 meters) increase in height. [1]
The environmental lapse rate (the actual rate at which temperature drops with height, dT / dz) is not usually equal to the adiabatic lapse rate (or correspondingly, e52ae677de914e5cfddd35c399e2c57b.png). If the upper air is warmer than predicted by the adiabatic lapse rate (dS / dz > 0), then when a parcel of air rises and expands, it will arrive at the new height at a lower temperature than its surroundings. In this case, the air parcel is denser than its surroundings, so it sinks back to its original height, and the air is stable against being lifted. If, on the contrary, the upper air is cooler than predicted by the adiabatic lapse rate, then when the air parcel rises to its new height it will have a higher temperature and a lower density than its surroundings, and will continue to accelerate upward.[1][2]
Temperatures decrease at middle latitudes from an average of 15°C at sea level to about -55°C at the beginning of the tropopause. At the poles, the troposphere is thinner and the temperature only decreases to -45°C, while at the equator the temperature at the top of the troposphere can reach -75°C
