Air can be humidified by passing through a long tube whose inside diameter is lined with a wick saturated with liquid water. The

device is shown below. In the process, air containing 1.0 mol % water vapor at 40°C and 1 atm total pressure enters a 3.0 cm inside diameter tube at a velocity of 3 m/s. Water evaporates from the wick as the air passes over it. Water adsorbent liner with 1.0 mm thick 0.6 g water/cubic cm liner. Gas stream velocity of 3 m/s, 1 atm and 40C D=3.0 cm L=8m There is no diffusion resistance of water vapor through the wick itself. The entire process is maintained at 40°C where the saturated vapor pressure of water is 55.4 mmHg. The viscosity of air under these conditions is 1.91 x 104_8_ and the density of air is 1.13 x 10-38. The cm-S diffusivity is 0.28
(i) Using a shell balance, develop a differential equation to predict the concentration of water vapor exiting the tube.
(ii) Integrate the equation you developed in (a) with the appropriate boundary conditions (or limits) to obtain the final form of the equation to predict the concentration of water vapor exiting the tube.
(iii) If the thickness of the wick lining the inner surface of the tube is 1.0 mm and it initially contains 0.6 g of water per cm'. If the tube is 8.0 m long and humidification occurs at 40°C and 1.0 atm pressure, determine the concentration of water vapor in the outlet air.
(iv) Determine how long the process can operate before the liquid water is depleted.

Describe and name the different types of collision. In which are the linear momentum and kinetic energy conserved
ipn [44]

Answer:

1. Elastic collision

2. Inelastic collision    

Explanation:

Elastic collision: collision is said to be elastic if total kinetic energy is not conserved and if there is a rebound after collision

the collision is described by the equation bellow

m1U1+ m2U2= m1V1+m2V2

Inelastic collision: this type of collision occurs when the total kinetic energy of a body is conserved or when the bodies sticks together and move with a common velocity

the collision is described by the equation bellow

m1U1+ m2U2= V(m1+m2)

What is the average power consumption in watts of an appliance that uses 5.00 kWh of energy per day? How many joules of energy d
denpristay [2]

Answer:

(A)  power  = 0.208 kW = 208 watts

(B)  energy = 6.6 x 10^{9} joules

Explanation:

energy consumed per day = 5 kWh

(a) find the power consumed in a day

         1 day = 24 hours

        power = \frac{energy}{time}

        power = \frac{5}{24}

          power  = 0.208 kW = 208 watts

         

(b) find the energy consumed in a year

    assuming it is not a leap year and number of days = 365 days

     1 year = 365 x 24 x 60 x 60 = 31,536,000 seconds

            energy = power x time

            energy = 208 x 31,536,000

            energy = 6.6 x 10^{9} joules
