Dry air is a mixture of what 5 gases? Which of the 5 is the most abundant (about 79%), and which is second (about 21%)? As an aside, the molecular weight of dry air is 28.97 lb/lbmol or kg/kgmol etc The Dalton model assumes that each component of an ideal gas mixture (recall PV=mRT) occupying a closed vessel (V) acts as if it were alone at the temperature (T) and volume (V). Furthermore, each component (i) is at a partial...

2) Very humid air enters a dehumidifier at 500 ft^3/min. The air is at a dry-bulb temperature of 85 degrees F and a relative humidity of 90%. The specific humidity of the mixture must be brought to 30 grains of water per pound mass of air. Assume atmospheric mixture pressure. A) How low must the dry-bulb temperature go to achieve this? B) What is the rate at which energy must be removed to accomplish the reduction in specific humidity, in...

1. Air at 95°F and 1 atm containing 0.0225 lbm H2O per lbm dry air is send to a condenser at the rate of 500 ft3 humid air per minute. (a) What is the mass flow rate of dry air in this feed stream (lbm/min)? (b) The air leaves the cooler saturated with water at 55°F and 1 atm. If the mass flow rate of dry air was 50 lbm/min, find the rate at which water is condensed from the...

3. During an experiment involving the flow of dry air at 30°C and 1 atm (101.325 kPa) at a free stream velocity of 5 m/s over a body covered with a layer of naphthalene. The incoming air is free of naphthalene, and thus the mass fraction of naphthalene in the free stream is zero (WAC). The vapor pressure of naphthalene at 30°C is 18.5 Pa and the diffusion coefficient of naphthalene in air at 30°C is 0.86 x...

a. Calculate the dry air and water vapor mass flow rates (lb/min) if the volume flow rate is 1,000 cfm, the humidity ratio is 0.025 lbv/lba, and the dry air density is 0.072 Iba/ft3. b. Assume the above air enters an evaporator coil at 90°F where it is cooled in a constant humidity ratio process until reaching the 100 % RH curve ( the temperature at that point is the dew point. The air then keeps dropping in temperature, following...

Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...
