The energy output of a blender is 1.4 kwh. if the blender is 85% efficient, how much energy is lost to the surroundings? kwh

0.3 Kwh

Explanation:

1) Data:

a) energy output = 1.4 kWh

b) efficiency =  85%

c) energy loss = ?

2) Formulas

a) efficieny = (energy output / energy input) × 100

b) energy loss = energy input - energy output

3) Solution

a) energy output

efficiency = (energy output / energy input) × 100 ⇒

energy input = energy output × 100 / efficiency = 1.4 Kwh × 100 / 85 ≈ 1.7 Kwh

b) energy loss = 1.7 Kwh - 1.4 Kwh = 0.3 Kwh.
