245 SOLVED PROBLEMS

Question: 12.6.1

A Drop-in Replacement for the Antifreeze Ethylene Glycol Water (with additives to protect against corrosion) circulates between the engine block and the radiator to cool automobile engines. Since water expands on freezing, if the water were to freeze in the engine block of a parked car in a

Question: 3.2-3

A Joule-Thomson or Isenthalpic Expansion A gas at pressure P1 and temperature T1 is steadily exhausted to the atmosphere at pressure P2 through a pressure-reducing valve. Find an expression relating the downstream gas temperature T2 to P1, P2, and T1. Since the gas flows through the valve rapidly,

Question: 10.1.6

A Very Simple Design of a Distillation Column Start with the the feed of the previous illustration, consisting of 50 mol % n-pentane and 50 mol % n-heptane, and recover 95 percent of the n-pentane in the feed in a stream that contains 98 mol % n-pentane. At the top of the column, 1 mole of product

Question: 14.3.2

Adiabatic Flame Temperature Calculation An equimolar gaseous mixture of benzene and ethylene at 300 K is fed into a reactor, where ethyl benzene is formed. If the reactor is operated adiabatically at a pressure of 1 bar, and the reactor effluent is in chemical equilibrium, find the reactor effluent

Question: 11.1.3

Air Stripping of Radon from Groundwater Groundwater from some geological formations may contain radon, a gas that has been implicated in lung disease, so its concentration should be reduced. Air stripping is one method of doing this. Groundwater from a well is found to contain 10 parts per million

Question: 7.4.2

Alternative Fugacity Calculation Use other data in the superheated vapor steam tables to calculate the fugacity of steam at 300°C and 8 MPa, and check the answer obtained in the previous illustration.

Question: 4.5-2

An Alternative Way to Solve One Problem Sometimes it is possible to solve a thermodynamic problem several ways, based on different choices of the system. To see this, we consider Illustration 3.4-5, which was concerned with the partial evacuation of a compressed gas cylinder into an evacuated cyli

Question: 5.3.2

Analysis of compressor operation An ideal gas with a constant pressure heat capacity of 30 kJ/kg K is to be compressed from 1 bar and 25◦C to 10 bar. (a) Compute the final temperature of the gas and the work required if the compressor operates isentropically (b) Compute the final temperature of the

Question: 9.3.2

Analyzing the Gibbs Energy of a Mixture to Determine Whether It Is an Ideal Mixture Experimentally (as will be described in Sec. 10.2) it has been found that the Gibbs energy for a certain binary mixture has the form Gmix(T,P,x) = Σi=1^2 xiGi(T,P) + RT Σi=1^2 xi ln xi + ax1 x2 (**) where a is a

Question: 8.9.2

Another Application of the Gibbs Phase Rule Determine the number of degrees of freedom for each of the following mixtures. a. A one-component vapor-liquid mixture b. A nonreacting two-component vapor-liquid mixture c. Avapor-liquid mixture of ortho-, meta-, and para-xylenes and ethylbenzene at
