Atmospheric air at 760 mm Hg is at 22°C dry bulb temperature and 20°C wet bulb temperature. Using the psychrometric chart, determine: a. Relative humidity. b. Humidity ratio. d. Enthalpy of air per kg dry air. e, Volume of moist air/kg dry air.

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.

For two objects at thermal equilibrium, which of the following is true?

1. They must be at the same temperature

2. They must have the same internal energy

3. They must have same enthalpy

4. None of these

Read all the following statements and mark the statement as your answer that best defines the heat capacity of a sample.

1. It is the amount of heat required to raise the temperature of unit mass by 1 ℃

2. It is the amount of heat required to raise the temperature of a substance by 1 ℃.

3. It is the amount of heat required to raise the temperature of a body by 100 ℃.

4. None of these
