$13.$ Pulverized Coal$-$Specific Energy Consumption:

A power plant uses a pulverized coal system to generate $200$ MW of electrical power. The coal used has an energy content of $29$ MJ$/$kg$.$ If the overall system efficiency $($from coal to electricity$)$ is $35\%,$ calculate the mass of coal required per hour.

$14.$ Flue Gas Analysis in Oil Burner:

An oil$-$fired boiler consumes $500$ kg$/$hr of fuel oil with a calorific value of $42$ MJ$/$kg$.$ If the flue gas analysis shows that for every kg of fuel burned, $15$ kg of flue gas is emitted, calculate the total flue gas production in one day.
