Answer 1

Question

Chapter 13.12, Problem 3E

Interpretation Introduction

Interpretation:

Find out the stable phase of the system and mass fraction of the co-existing phases.

Concept introduction:

Mass to mole conversion is given as follows:

ni=miM.Wi

Here, mass of the component is mi and molecular weight of the component is MWi.

Molecular weight of ethylene glycol n-butyl ether is 118.17 g/mol.

Molecular weight of water is 18.01 g/mol.

The composition of this mixture in terms of percentage is given as follows:

xi=nini+nw×100%

Here, mole of the component is ni and mole of the water is nw.

A closed system of 122 moles of an ideal gas with constant-pressure heat capacity of cp = 2.5R expands isobarically from 52°C and 4.9 bar to 137°C, with a thermodynamic efficiency of 0.74. How much total work is involved in this process? Please report your answer to the nearest whole kJ and don't forget the sign: "-" if the work is negative, no sign if the work is positive.

Liquid toluene at 20°C is reversibly and isothermally compressed from 2.94 bar to 7.7 bar. What is the specific work, in J/kg, required to accomplish this? Some properties of liquid toluene at 20°C: β = 1.05 x 10-3 ºC-1 , κ = 8.96 x 10-5 bar-1 , V = 1154 cm3 kg-1. Please report your answer to 3 SF. Be very, very careful of units!
