Please draw a flowchart

Air at 86F and 80% relative humidity is delivered to a cooling unit by means of a 6-inch internal diameter circular duct. The velocity of this air in the duct is 1000 feet per minute. In the unit, the air is cooled to 59.9F, condensing some of the water in the air. Determine the flow rate of the condensed water and the amount of energy that must be removed from the unit.

Butane is burned with air. No carbon monoxide is present in the combustion produets.
Calculate the molar composition of the product gas for each of the following three cases: (i)
theoretical air supplicd, 100 % conversion of butane: (i) 20% excess air. 100% conversion of
butane: and (il) 33% excess air. 90% conversion of butane.
