Determine the molar flow rate of the exhaled dry air, the mol% of water vapor in the exhaled air, and the mass flow rate of the exhaled dry air. Then determine the correct choice below.

Determine the work done in the reactive process and then choose the correct option.

Determine the molar flow rate of the inhaled air, the vapor pressure of water, and the mol% of water vapor in the inhaled air.  Then determine the correct choice below.

Using an appropriate reference state for dry air and H2O, determine the total input rate of enthalpy (

The heat of vaporization of magnesium chloride is 136.8 kJ/mol at 1418oC.  The internal energy change on vaporization is approximately

Problem Statement for next 5 questions: On a cold winter day the temperature is 6oC and the relative humidity is 20%.  A person inhales air at an average rate of 5000 mL/min and exhales a gas saturated with water at near body temperature of 36oC. Additionally, the person ingests water into the body as a liquid at 25oC. Assume that: mass flow rates of the inhaled and exhaled dry air (excluding water) are the same the heat capacity (Cp) of the water-free dry air is each 1.05 J/(g oC) treat breathing as a continuous, steady process (inhaled air and liquid water enter, exhaled breath exits) and neglect work done by the lungs enthalpy of subcooled water can be approximated by saturated liquid water assume dry air is 791 mol% nitrogen and 21 mol% oxygen Excerpt of saturated steam table is given below
