Answer:
The heat loss is
Explanation:
From the question we are told that
The thickness is
The inner temperature is
The outer temperature is
The length of the window is L = 1 m
The width of the window is w = 3 m
Generally the heat loss is mathematically represented as
Where k is the thermal conductivity of glass with value
and A is the area of the window with value
substituting values
There are many factors which contributes as to how a machine will be processing the input energy and convert it to output energy. Even with identical mechanism, these factors will have major effect on the output. Some factors are deflection, friction and wear. Some system maybe exposed to poor lubrication than the other which'll produce more friction and wear thus lower mechanical advantage.
135 amps
Current is voltage multiplied by power
