A portable generator produces 2.5 kW ofmechanical work with an efficiency of 0.20 to supply electricityat a work site. (a) If the efficiency is increased but the work outputremains the same, will the rate of fuel consumption by the engineincrease, decrease, or stay the same? Explain. (b) Will the rate ofwaste heat emission increase, decrease, or stay the same? Explain.(c) Calculate the rates of fuel consumption and waste heat emission for engine efficiencies of 0.20 and 0.30
