Question 1.
Kinetic Energy is given by the formula: KE = 1/2mv²where m = 100 kgv = 12.5 m/s
Substitute the values into the formula: KE = 1/2 (100 kg) (12.5 m/s)²KE = 1/2 (100 kg) (156.25 m²/s²)KE = 7812.5 J
Question 2 Given:
Pore porosity of the core = 0.28Dry weight of the core = 156.4 g
Weight of the core when saturated with a 0.75 g/cm³ oil = 175.9 g
(a) Pore volume of the core. To get the pore volume of the core, you need to find out the volume of the oil that the core absorbs. Density = mass/volume Rearrange the formula to obtain the volume: Volume = mass/density Volume of oil absorbed = (175.9 g - 156.4 g) / 0.75 g/cm³Volume of oil absorbed = 26.0 cm³Since the core has a porosity of 0.28, the pore volume of the core will be:0.28 x 26.0 cm³ = 7.28 cm³
Therefore, the pore volume of the core is 7.28 cm³.
(b) Bulk volume of the core The bulk volume of the core is obtained by dividing the mass of the core by its density. Density = mass/volume Rearrange the formula to obtain the volume: Volume = mass/density Bulk volume of the core = 156.4 g / (0.75 g/cm³)Bulk volume of the core = 208.53 cm³Therefore, the bulk volume of the core is 208.53 cm³.

The outlet gases to a combustion process exits at 478°C and 1.01 atm. It consists of 1.93% H₂O(g), 6.77% CO2, 14.64% O2, and the balance is N₂. What is the dew point temperature of this mixture? Type your answer in °C, 2 decimal places.
The dew point temperature of the gas mixture is -4.57°C.
The dew point temperature is the temperature at which the gas mixture becomes saturated with water vapor, resulting in the condensation of water droplets. To determine the dew point temperature, we need to calculate the partial pressure of water vapor in the gas mixture.
Calculation of the partial pressure of water vapor:
The total pressure of the gas mixture is given as 1.01 atm. To find the partial pressure of water vapor, we need to convert the mole fraction of water vapor (1.93%) to a decimal fraction. Assuming a total of 100 moles of the gas mixture, we have:
Moles of water vapor = 1.93/100 * 100 = 1.93 moles
Partial pressure of water vapor = Moles of water vapor / Total moles * Total pressure
Partial pressure of water vapor = 1.93 / 100 * 1.01 atm = 0.019613 atm
Calculation of the dew point temperature:
To calculate the dew point temperature, we can use the Antoine equation, which relates the saturation pressure of water vapor to the temperature:
log10(P) = A - (B / (T + C))
where P is the saturation pressure of water vapor, T is the temperature in degrees Celsius, and A, B, and C are constants specific to water.
Rearranging the equation, we get:
[tex]T = (B / (A - log10(P))) - C[/tex]
For water vapor at atmospheric pressure, the Antoine equation constants are:
A = 8.07131
B = 1730.63
C = 233.426
Substituting the values into the equation, we have:
T = (1730.63 / (8.07131 - log10(0.019613))) - 233.426
T ≈ -4.57°C

Free benzene from a scrubber's coal gas is recovered by passing a solution of benzene and scrubbing oil through a tower in contact with the steam. The entering liquid stream contains 8 mol% benzene. It is desired to recover 80% of the benzene using a vapor ratio that is 1.4 times the minimum ratio. An expense in the washing oil (benzene-free liquid solvent) of 6.94 mol/s will be used.
determine the required moles of steam per second if
a) a parallel draft tower is used
b) a tower downstream
The moles of steam required for the parallel draft tower is - 33.90 mol/s. The moles of steam required for the downstream tower is 99.45 mol/s.
a) For the parallel draft tower
In parallel draft tower, benzene will be stripped from scrubbing oil by direct contact with steam. From the given data,It is desired to recover 80% of the benzene i.e. n (Benzene) recovered = 0.8 x n(Benzene) entering at the top
Thus, the flow rate of benzene entering at the top of the column, n(Benzene) entering = 6.94 x 0.08 = 0.555 mol/s
Also, Vapor ratio is given as,VR = 1.4 times the minimum ratio
Thus, the minimum ratio, MR = VR / 1.4 = 1 / (ER - 1)where, ER is the equilibrium ratio For Benzene and steam at the given temperature, ER = 0.142 ER = n(Benzene) in liquid / n(Benzene) in vapor The benzene concentration in liquid stream entering the tower is 8 mol%
Thus, n(Benzene) in liquid = 6.94 x 0.08 = 0.555 mol/s
Therefore, n(Benzene) in vapor = n(Benzene) in liquid / ER = 0.555 / 0.142 = 3.9 mol/s
Thus, Total vapor leaving the column, n(Vapor) = 3.9 / (ER - 1) = 3.9 / (0.142 - 1) = - 33.90 mol/s
This negative sign shows that the steam is being absorbed by the liquid and hence, a parallel draft tower is not feasible.
b) For the downstream tower
In the downstream tower, scrubbing oil will be stripped of benzene by countercurrent flow with steam. Thus, the benzene content in the scrubbing oil will decrease from top to bottom. Thus, the design equation for the downstream tower is given as,L/V = ln(1 + ER [xB/(1 - xB)] )where, xB is the benzene concentration in the oil entering the tower.
Since 80% of the benzene has to be removed from the oil, xB leaving the tower = 0.2 x xB entering the tower
Thus, xB entering = 0.08, xB leaving = 0.016The expense of scrubbing oil, L is given as 6.94 mol/s. The flow rate of steam, V is to be calculated. Thus, 6.94/V = ln(1 + ER [xB/(1 - xB)] )
On substituting the given values and solving, V = 99.45 mol/s
Therefore, the moles of steam required for the downstream tower is 99.45 mol/s.
