This is given from my notes:Power GenerationOil - 40% efficient; CO2 Emissions (g/mol) 70 g/molNatural gas - 23% efficient; CO2 Emissions (g/mol) 50g/molCoal - 23% efficient; CO2 Emissions (g/mol) 90 g/molEnergy Density of various sources (In heat of combustion -MJ/kg)Coal - 30 MJ/kgDiesel - 45 MJ/kgGasoline - 47 MJ/kgKeronsene - 46 MJ/kgNatural Gas - 39 MJ/kg @ STPWater - 10,000 J/m3Please Show all work and give as much details aspossible.Questions:
A coal power plant is 23% efficient. If it produces 50MW of power, how much energy does it actually consume persecond? Per hour? Per Day?
How much coal does it burn to do this (I think you need thetable I wrote at the top)
How much CO2 is produced per second? Per hour? Per day?
