What is a negative effect of the jet engine?
Noise pollution would be one.
How are any waste materials and or products transferred stored and disposed of?
Many waste materials end up in landfills. This causes pollution and excessive littering in the environment. Harsh chemicals are often spilled into the ground as well.
Do you think the positive effects of mechanizing the manufacturing process outweighed the negative effects?
I think the negative outweigh the positive because there are poorer working conditions, pollution, the breaking up of families and/or communities as well as the loss of family businesses.
What is the stack height of 1250 kva diesel generator set?
what should be height of stack of 1250 kva D.G as per Indian pollution boardA: it should be 7.1 meter + building height of 1250kva Dg set installed.
2 stroke vs 4 stroke?
On a 2 stroke engine, each cylinder fires every time the piston comes up. On a 4 stroke engine, the cylinder only fires every OTHER time the piston comes up. 4 stroke engines have 4 strokes: Intake, compression, power, and exhaust. 2 stroke engines complete these cycles in only two strokes of the piston by use of ports in the cylinder walls. 2 stroke engines usually produce more power for a given weight/size. But, in gasoline engines, 2 stroke engines are typically less efficient (use more gas) and have much higher pollution levels (note: some newer "direct injection" 2 stroke engines do much better on pollution levels than the typical 2 stroke)
How super fast jet planes rockets has caused the enviormental pollution?
Sulfur particulate and contrails from aircraft can produce high altitude pollution
What does the cloud name contrails mean?
Contrails is a shortening of condensation trails.
Do airplane contrails affect the weather?
No it is the weather that facilitates the production of contrails.
What are jet contrails?
Jet contrails are water condensation resulting from the rapid compression and decompression of the air around the wing as the airplane moves through the atmosphere. The atmospheric conditions have to be just right for contrails to occur, and that is why you sometimes see contrails seem to wink off and on, as the airplane passes through drier air the contrails will stop.
What are contrails?
contrails are "clouds" formed by the hot, humid air from plane/jet engines which mixes with water vapor high in the sky, then turning into ice crystals which then create contrails.
What is the mission of the airplanes that leave contrails?
To be an airplane with jet engines? All jet airplanes leave contrails.
What is an anthropogenic cloud?
An anthropogenic cloud is a cloud formation that is a result of human activities, such as industrial processes, pollution, or aircraft emissions. These clouds can have impacts on weather patterns, climate change, and air quality.
What types of planes leave contrails?
Any kind of powered airplane can leave contrails under the proper condition. Rocket planes always leave contrails. Jets usually leave contrails but may not if the atmospheric conditions are not right. Even internal combustion engine planes can leave contrails if they operate at very high altitude and the atmospheric conditions are just right.

What is airplane smoke trail called?
Contrails
What are jet contrails made of?
water vapor
Are contrails similar to cumulonimbus clouds?
No. Contrails are long, narrow, thin clouds left by aircraft at high altitude. Cumulonimbus clouds are enormous, thick, towering storm clouds.
What is an airplane smoke trail called?
Contrails or condensation trails
