Problem 1: a) What is the residual volume of saturated liquid water at 1 bar? b) Estimate the residual volume of ethanol vapor at 1 bar and 100 °C. c) Use the generalized graphs to calculate the entropy change of 1 mole of ethanol undergoing isothermal compression from 1 bar to 100 bar along the critical isotherm. Problem 2: n-Octane is compressed reversibly at constant temperature along the critical isotherm until the critical point is reached. The initial pressure is 1 bar. The pressure takes place in a closed system. Use the Lee-Kesler method to calculate the following: a) What is the entropy change of n-octane? b) Calculate the heat that must be supplied to the system to maintain isothermal conditions. c) Calculate the necessary amount of work.
air at 4mpa and 3000c enters a will insulated turbine operating at steady state with negligible velocity. the air
Forty-five kilograms of a solution containing 30 wt% ethylene glycol in water is to be extracted with furfural. Using Figures 4.14a and 4.14c, calculate:
question 1 two well of radius 18 inches are constructed in a confined aquifer 150 ft thick with hydraulic conductivity
A 100.0-L aliquot (portion) of this solution is diluted to a final volume of 100.0 mL. Calculate the concentration of the final solution in terms of molarity.
A continuous filter is used to separate a clear filtrate from alumina particles in a slurry. The slurry has 30% by weight of alumina (specific gravity of alumina = 4.5). The cake retains 5% by weight of water. For a feed stream of 1000 kg/hr, determi..
If an externally applied electric field produces a 5% expansion of the lattice, compute the dipole moment for each Na+-Cl- pair. Assume that this material is completely unpolarized in the absence of an electric field.
Zirconium is one of the few metals that retains its structural integrity upon exposure to radiation. The fuel rods in most nuclear reactors therefore are often made of zirconium.
50. Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor. The fresh feed to the process contains 32.0 mole% CO, 64.0% H2, and 4.0% N2. This stream is mixed with a recycle stream in a ratio S mol recycle/1 mol fresh feed to..
Crude dichlorobenzene is pumped from a storage tank to a distillation column. The tank is blanketed with nitrogen and the pressure above the liquid surface is held constant at 0.1 bar gauge pressure. The minimum depth of liquid in the tank is 1 m.
design a heat exchanger for the following dutyreduced crude oil leaving a distillation unit with a flow rate of 3166.04
A hydrocarbon liquid fuel (containing only C and H2) is burnt in air which produces a flue gas which analyses ( orsat analysis ) on dry basis as CO2 =10.5% , O2 = 5% and N2 =84.5%.
A sealed rigid tank is filled with 1 kg of steam at 200 °C and 10 bar. What is the volume of the tank? 0.5 kg of steam are removed from the tank. If the temperature remains at 200 °C, what is the new pressure in the tank?
