Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
The condition for maximum efficiency of a d.c. machine is that VARIABLE LOSSES must be equal to CONSTANT LOSSES i.e., variable losses = constant losses..
The electric space heater. It's the only common machine that's 100% efficient.
In any machine, some energy will usually be wasted. This will reduce the efficiency below the theoretical maximum of 1.0. However, please note that, if the efficiency is above 95% (or 0.95), when rounded to the nearest tenth you will get 1.0.In any machine, some energy will usually be wasted.

No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.
Mathematically, efficiency = (energy output) divided by (energy input) as a percentage. As if we couldn't figure this out for ourselves, one of the laws of Thermodynamics formally tells us "You can't get more energy out than what you put in." Applying this law to the formula for efficiency, it says that the maximum possible efficiency is 100%. However, the next law of Thermodynamics says "You can't even get that much out."
The plan was carefully orchestrated to insure success. He orchestrated every movement to get the maximum efficiency from the machine.
the efficiency is maximum in a transformer when no load loss is equal to load loss.
It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.
They're relatively light weight, and they have a concentrated fuel source. They have a narrow speed range of maximum efficiency, and they spew fumes.
It is maximum at about 75% to 100% of the motor rated load. Efficiency is maximum at unity power factor , when R=X and when variable losses Is equal to constant losses at rated load.
The main advantage of using a manual express machine is that you control the machine entirely, and make the coffee as strong or as weak as you like it.
