Gasoline in a fuel tank has been contaminated with water from condensation. Tech a says it will stay on the surface of the fuel and can be skimmed (removed) off. Tech b says that it will dissolve in the gasoline and be burned during the combustion process. Who is correct?

Diesel Fuel C14.4H24.9 is burned with atmospheric air in a stoichiometric ratio. The number of moles of N2 is?

Define the combustion equipment efficiency.

assume the φ =0.5

6. An elevator has a mass of 4500 kg. and can carry maximum load 1800 kg. If the elevator moves up, it carries the maximum load, at a speed of 3.8 m/s. determine the power required for the elevator to maintain that speed.

.) A 300 MW pulverized coal-fired power plant of 42% efficiency uses coal with an ash content of 19% and a neating value of 24,000 kJ/kg. Assume 28% of the ash content goes up the stack as particulate matter in the flue gas. The PM emission is controlled by an ESP which has the following efficiencies and weight distribution in the given size ranges. Find the fly ash emitted in g/s. size efficiency (%) wt% in flue gas 0-5 70 7 5-10 92.5 19 10-20 96 21 20-40 99 24 >40 100 29
