Question

a fuel mixture of 60 percent by mass methane (ch4) and 40 percent by mass ethanol (c2h6o) is burned completely with theoretical air. if the total flow rate of the fuel is 10 kg/s, determine the required flow rate of air.

Answer 1

The most common unit of air velocity (distance traveled in a unit of time) is feet per minute (FPM).

You may calculate the amount of air passing past a location in a duct in one unit of time by multiplying the air velocity by the area of the duct. The usual unit of volume flow measurement is cubic feet per minute (CFM). The usual unit of volume flow measurement is cubic feet per minute (CFM). Flowmeter for measuring airflow: A hot wire anemometer measures the heat loss from a wire that has been electrically heated and placed in the air stream to determine the velocity and direction of a fluid (in this case, air). The amount of gas passing through a specific site in a specific amount of time is known as the gas flow rate.
