43 lb. moles of CO2, 6 lb. moles of water vapor and 195 lb.
moles of N2 and 10 lb. moles of oxygen flow from a stack at 121 C.
What is the partial pressure of water vapor in the flue gas in mm
Hg.
Q: A mixture of 0.423 moles of N2 and 5.73 moles of
CO2 has a total pressure of 777 torr. What is the
partial pressure of N2?
Please give the details of the ploblem, thanks.
Calculate the energy required to convert 100 kg of ice at 0
degrees C and 1 atm. to water vapor at 650 degrees C and 60 bar.
The heat of fusion of ice is 333.6 J/g at 0 degrees C.
Suggested path: i) convert the ice from solid to liquid, ii)
heat the liquid to the boiling point, iii) convert the saturated
liquid to a saturated vapor, iv) heat the vapor to the final
temperature, v) pressurize the gas to...
2.00 moles of CO2 and 1.50 moles of H2 are placed into a rigid
5.00-L container and they react according to the equation ? ?
CO2(g) + H2(g) ? CO(g) + H2O(g) ? ? K = 2.50 What will be the
concentration of carbon monoxide when equilibrium is reached?
Acetic acid is to be extracted from benzene into water at 25C.
100 kg/h of a feed that is 0.0092 wt. fraction acetic acid and
0.9908 wt. fraction benzene is fed to a column. The inlet water is
pure and flows at 25 kg/h. The desired outlet weight fraction is
0.00040 acetic acid in benzene. Assume total flow rates are
constant, water and benzene are completely immiscible, eqilibrium
is linear.
K=y/x = wt. fraction solute in extract/wt. fraction solute in...
Combustion analysis of 1.500 g of a sample produced 0.0468 moles
of CO2(g) and 0.0936 moles of H2O(g).
Which substance is consistent with this analysis?
A 100-lb driver and a
2000-lb tractor lift 900 lb of gravel. Create a MATLAB program that
will:
Determine the reaction at each of the two rear wheels and two
front wheels.
The shift has changed and a new driver dumped some of the
gravel. Ask the user the weight of the new driver and the weight of
the gravel left in the tractor.
Calculate the new reaction at each of the two rear wheels and
two front wheels.

3.) Product with Cp = 0.75 Btu/lb°F is flowing at a rate of 3300
lb/h and has to be cooled from 221°F to 160°F. ? Cooling water at
60°F at a mass flow rate of 10,000 lb/h is used. ? The overall U of
the heat exchanger is 115 Btu/h ft2 °F. Calculate the outlet water
temperature (will be the same for both) ____________________ and
the heat exchanger area for: A co-current flow shell-and-tube heat

One hundred moles of moist air (100 moles) at 25oC and 100 kPa
has a dew point of 16oC. If you want to remove 50% of the initial
moisture in the air (at a constant pressure of 100 kPa).
1. Sketch the process.
2. Determine to what temperature should you cool the air? Assume
that after removal of 50% of moisture from the air, the final air
is saturated.
Water at a flow rate of 20,000 kg/h will be heated from 20°C to
35°C by hot water at 140°C. A 15°C hot water temperature drop is
allowed. A number of 3.5 m hairpins of 3 in. (ID = 0.0779 m) by 2
in. (ID = 0.0525 m, OD = 0.0603 m) counter flow double-pipe heat
exchangers with annuli and pipes, each connected in series, will be
used. Hot water flows through the inner tube. Fouling factors are:
