What is the Formula for calculating the efficiency of a machine?
Efficiency = Output value / Input valueFor example, if a machine needs 10 KW to run and produces 8 KW, its power efficiency is 8/10 = 0.8 or 80%Efficiency is always between 0 and 1 (or 0 and 100 if expressed as a percentage.)
What is equal to the output work divided by the input work?
That is called the machine's efficiency. It is a number between 0 and 1 (or between 0% and 100%).
Efficiency of packing of object of different shapes?
The efficiency of packing of objects relies on the shape of the objects. There are two factors to take into account: empty space between objects (which cannot be avoided due to the object shape) and empty space around the outside of the objects and the packing container.
What is the difference between actual machanical advantage and ideal machanical advantage?
Ideal mechanical advantage is what could be obtained without the effects of gravity and friction lowering the efficiency of the machine. The actual mechanical advantage is what can actually be obtained by the machine.
What is the length of the eurotunnel?
Eurotunnel is the name of the company which owns and operates the Channel Tunnel, as well as other business interests. The Channel Tunnel runs between Folkestone and Sangatte, near Calais. Channel Tunnel length is about 50 Km of which 38 Km are below the water. 50.5 km (31.4 mi)
Which is an impossible value of efficiency for a heat engine?
100% efficiency is impossible for a heat engine working between two reservoirs at different temperatures according to the second law of thermodynamics.
What happens to the efficiency of a heat engine when the temperature of the reservoir into which heat energy is rejected is lower?
The efficiency of a heat engine increases when the temperature of the reservoir into which heat energy is rejected is lower. This is because a lower temperature of the sink allows for a greater temperature difference between the hot and cold reservoirs, which leads to a higher efficiency according to the Carnot efficiency formula.
Limitations of the Carnot cycle for the operation of the steam power plant?
The Carnot cycle gives the theoretical maximum efficiency of an engine operating between two heat reservoirs. The Carnot cycle is an idealized engine cycle that is thermodynamically reversible. Real systems such as power plants are not reversible, and the entropy of a real material changes with temperature (which is not accounted for by the Carnot cycle). A steam power plant operates closer to a cycle known as the Rankine cycle.
Which terms best describes the rate of movement of carbon between reservoirs?
constant
What is Any movement of carbon between carbon reservoirs is called?
This movement of carbon between carbon reservoirs is called carbon cycling. It involves processes such as photosynthesis, respiration, decomposition, and combustion that transfer carbon between the atmosphere, oceans, plants, soil, and animals.
Find the relationship between internal efficiency and school size?
Find the relationship between internal efficiency and school size?
Which of thr following is not involved in the movement of matter and energy between reseevoirs?
Photosynthesis is not involved in the movement of matter and energy between reservoirs. Photosynthesis is a process by which plants convert sunlight, water, and carbon dioxide into oxygen and glucose, but it is not directly involved in the movement of matter and energy between different reservoirs in an ecosystem.
What cycles involve the movement of matter and energy between reservoirs?
Biogeochemical cycles, such as the carbon cycle, nitrogen cycle, and water cycle, involve the movement of matter and energy between reservoirs in the Earth system. These cycles are essential for the functioning of ecosystems and sustaining life on Earth.
What is mean of pump efficiency?
The ratio between the energy efficiency of pumps and pump uses the energy that does. Pump efficiency is determined by the manufacturer. In the calculation of pump efficiency is 70%.
Difference between technical efficiency and economic efficiency?
technical efficiency is related to change in output due to change in input and economic efficiency refers to a number of related concepts.
What is the Meaning of management efficiency and effectiveness?
Between efficiency and effectiveness which one is more important for performance
