What determines the coefficient ratio used to predict the amount of product produced from any given amount of reactant?
The reaction equation gives the RATIO of moles reactant to moles product. With known molar mass the (mass) yield can be calculated. (Of course other reactants are to be in excess! for complete reaction of the reactant involved for this yield)
What is stripping Ratio and how is it calculated?
It's a ratio of waste extracted at a mine and is expressed as: (Total extracted - Mineral for plant) / Mineral for plant -m0id.
How are trophic level efficiency measured?
Trophic level efficiency is the ratio of production of one trophic level to the production of the next lower trophic level. This efficiency is never high.
Is not related to a cells ratio of surface area to volume?
cell size rate of growth number of nuclei efficency of cell's transport of oxygen efficiency of cell's transport of nutrients
What is the efficiency of hydraulic generators?
Basically, you need to calculate the amount of energy contained in the fuel you use to produce a given amount of electrical energy. To calculate the amount of energy in the fuel you need to lookup the number of thermal energy units per unit volume then you can convert those thermal energy units into Joules (1 gallon [U.S.] of diesel oil = 146 520 000 joules - www.onlineconversion.com) The on the electrical side, just multiply the voltage by the current by the number of seconds of run time (unvarying load) to get the electrical power output in Joules. Then the efficiency is just the the output power divided by the input power (x100 for %).
What is an efficiency ratio?
The efficiency ratio for a machine usually refers to the ratio of the useful energy available from a machine and the energy put into it.
What is the ratio of work put out of a machine to the work put in is its?
It is the efficiency of the machine.
The ratio of output compaired to in input?
It is the efficiency of a machine.
The efficiency of a real machine?
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.
When discussing engines the ratio of output work to input work expressed as a percentage is called .?
The efficiency of the machine.
What is the efficiency of the machine?
a machine applies a force of 100 newtons over a distance of 10 meters to raise a500 newtons drum 1.5 meters. what is efficiency of the machine ?
What is the ratio of the energy a machine delivers to the energy supplied to it?
efficiencyThe ratio of useful energy to total input energy is called efficiency. It refers to the percentage of the work input that is converted to work output.
What is the relationship between ideal mechanical advantage and velocity ratio?
The ratio of Mechanical Advantage and Velocity Ratio is Efficiency. That is to say the ratio of M.A. and V.R. is constant.
The ratio of output force to input force for a simple machine is called its advantage?
The answer is mechanical advantage, not efficiency!
Describe why a high-efficiency machine is more desirable than a low-efficiency machine?
Efficiency is the ratio of the energy converted into useful work by the machine to the energy supplied to the machine. Certainly it will not be possible to convert all the energy supplied into useful work because of wastage of energy due to so many reasons. So efficiency will be always less than 1. As the efficiency becomes more the loss would become less. Hence it is desirable.
How do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
What does energy efficiency?
Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.
