<span>Engineers place tolerance on dimensions since
the when engineers use tolerance, buildings and constructions projects like
tall towers, roads, and bridges become more reliable, strong and stable. In
harnessing tolerance, the end product that is made by the engineers,
specifically buildings like schools, hospitals, malls and skyways are sturdy
and dependable.</span>
Coefficient of performance or more commonly known as COP is calculated through the equation,
COP = ((T₂)/(T₂ - T₁))
where T₂ is the hot temperature and T₁ is the cold temperature. Similarly, these can also be,
COP = heat ejected / (heat ejected - heat provided)
Substituting,
COP = 22,000 / (22,000 - 15,000) = 3.14
Thus, the value of the COP is approximately 3.14.
