What are the environmental impacts of renewable energy? The environmental impacts associated with solar power can include land use and habitat loss, water use, and the use of hazardous materials in manufacturing, though the types of impacts vary greatly depending on the scale of the system and the technology used—photovoltaic (PV) solar cells or concentrating […]

How is thermal efficiency of Otto cycle calculated? When we rewrite the expression for thermal efficiency using the compression ratio, we conclude the air-standard Otto cycle thermal efficiency is a function of compression ratio and κ = cp/cv. What is the formula for compression ratio of the Otto cycle? For example, let assume an Otto […]

What does it mean when you think everyone hates you? paranoia How do I stop feeling hatred? If you feel hatred toward a person or group you don’t understand, lead with empathy (the ability to understand and share the feelings of another) and compassion (engaging in an act of kindness).

What is the theoretical maximum efficiency of the wind turbine? The third question was to determine the maximum possible conversion efficiency of a wind turbine. This was determined to be 59.26%. This value was first introduced by German engineer Albert Betz in 1919 and is known as The Betz Limit. Practical turbines have efficiency factors […]
