1. The problem statement, all variables and given/known data A power plant consumes 20,000 tons of coal per day; the average heat value of the coal used is 26,000 Btu/kg and the overall efficiency is 28%. What s the average electrical power output of the plant in kilowatts? How much heat is dissipated per day, in Btus? 2. Relevant equations I think that this equation may be helpful, but I'm not sure---P=E/t 3. The attempt at a solution I realized that I must get the units into pounds, so I converted the tons into pounds and got 400,000. I also thought of dividing by 24 since 24 hours is the time frame, and power is granted by energy over time. However, I think that my attempt at this problem is totally wrong. I'd greatly appreciate your help.
