Find the right answer of the following question

Question- Assume that the turbines at a coal-powered power plant were upgraded resulting in an improvement in efficiency of 3.94%. Assume that prior to the upgrade the power station had an efficiency of 47%, and that the heat transfer into the engine in one day is still the same at 1.73 x 1014 J.

Part 1- How much more electrical power is produced due to the upgrade?

kW

Part 2- How much less heat transfer occurs to the environment due to the upgrade?

J
