A $75-$hp $($shaft output$)$ motor that has an efficiency of $91\mathrm{.}0$ percent is worn out and is replaced by a high$-$efficiency $75-$hp motor that has an efficiency of $95\mathrm{.}6$ percent. Determine the reduction in the heat gain of the room due to higher efficiency under full$-$load conditions.$($Round the final answer to three decimal places.$)$

The reduction in the heat generation of the room due to higher efficiency under full$-$load condition is

W$.$
