Why The Actual Thermal Efficiency Is Always Less Than The Carnot Efficiency?

Why The Actual Thermal Efficiency Is Always Less Than The Carnot Efficiency? Answer 1: Real heat engines transferring energy between two reservoirs are less efficient than Carnot heat engines. This is a consequence of the fact that real heat engines undergo irreversible processes, and irreversible processes are less efficient (transfer less heat energy for a

How Hot Should Water Heater?

How Hot Should Water Heater? Professionals recommend keeping your water heater set at a temperature between 130 and 140 degrees Fahrenheit. Any higher, or lower, could actually be dangerous for you and your family. While turning the temperature up higher can result in burns, turning it lower than the recommended setting can also be dangerous.

At What Point Is The Temperature In Fahrenheit Three Times That In Celsius?

At What Point Is The Temperature In Fahrenheit Three Times That In Celsius? 80 = 3*26.667, so the degrees in Fahrenheit is 3 times the degrees in Celsius. At what temperature the reading on Fahrenheit scale is thrice that on Celsius scale? Answer: So, 160 degrees Celsius will equal 320 degreesFahrenheit. At what point is

Why Was Greenland Warmer 1000 Years Ago?

Why Was Greenland Warmer 1000 Years Ago? Although researchers have long known these two periods — the early Holocene and Last Interglacial — experienced warming in the Arctic due to changes in Earth’s orbit, the mix of fly species preserved from these times shows that Greenland was even warmer than previously thought. Why was it

Why Is It Called Delta T?

Why Is It Called Delta T? Delta-T, often marked as ΔT (Δ – the Greek letter Delta), is a way of expressing temperature differences when conducting temperature tests and cooling performance comparison. Officially, ΔT is used in precise timekeeping measurement, since „T“ can stand for „time“, so don’t get confused if you see it somewhere
