Chapter 9, Problem 9.79P
Interpretation Introduction

(a)

Interpretation:

The mole fraction of product composition to be calculated. Also, the percent conversion of CO and H2 is to be determined.

Concept introduction:

For a single reaction system, the final moles of each of the components present, can be estimated by the equation:

ni=nio+viξ ...... (1)

Here, ni is the final moles of the component i, nio is the initial moles of the component i, vi is the stoichiometric coefficient of the component i in the reaction and ξ is the extent of the reaction. vi is taken as negative for reactants and positive for products.

Mole fraction (yi) of any component is given by:

yi=nini ...... (2)

Here, ni represents the moles of the component, whereas i and ni represent the total moles of all the components present in the mixture.

Interpretation Introduction

(b)

Interpretation:

By neglecting the effect of pressure on enthalpies, the amount of heat added or removed from the process should be determined.

Concept introduction:

The amount of heat transferred is,

Q=outnH^iinnH^i

Here,

outnH^i is the heat of formation of product.

innH^i is the heat of formation of reactant.

The enthalpies of reactants and products depends on the heat capacity and temperature.

Interpretation Introduction

(c)

Interpretation:

The extent of reaction along with the amount of heat removed with the values of temperatures ranging from 200Cand400oC with increments of 50C should be determined. Also, the value of adiabatic reaction temperature should be calculated.

Concept introduction:

The amount of heat transferred is,

Q=outnH^iinnH^i

Here,

outnH^i is the heat of formation of product.

innH^i is the heat of formation of reactant.

The enthalpies of reactants and products depends on the heat capacity and temperature.

Interpretation Introduction

(d)

Interpretation:

The effect of pressure on the reaction with the help of extent of conversion and rate of heat transfer at 1 MPa and 15 MPa should be determined.

Concept introduction:

For a single reaction system, the final moles of each of the components present, can be estimated by the equation:

ni=nio+viξ ...... (1)

Here, ni represents the final moles of the component i, nio represents the initial moles of the component i, vi is the stoichiometric coefficient of the component i in the reaction and ξ is the extent of the reaction. vi is taken as negative for reactants and positive for products.

Mole fraction (yi) of any component is given by:

yi=nini ...... (2)

Here, ni represents the moles of component i and ni represents the total moles of all the components present in the mixture.

Interpretation Introduction

(e)

Interpretation:

The purpose of selecting initial condition of 250C and 7.5MPa for the results obtained from part (c) and (d) should be explained.

Concept introduction:

Adiabatic flame temperature helps to determine the completion of process. Adiabatic flame temperature occurs in two phases that is constant volume process and constant pressure process.

This temperature is applicable when the process takes place in an adiabatic condition which means no exchange of heat with the surrounding.

For a single reaction system, the final moles of each of the components present, can be estimated by the equation:

ni=nio+viξ ...... (1)

Here, ni represents the final moles of the component i, nio represents the initial moles of the component i, vi is the stoichiometric coefficient of the component i in the reaction and ξ is the extent of the reaction. vi is taken as negative for reactants and positive for products.

Mole fraction (yi) of any component is given by:

yi=nini ...... (2)

Here, ni represents the moles of component i and ni represents the total moles of all the components present in the mixture.

Ex. HW. A vertical glass tube, 2cm ID & 5m long in heated uniformly over its length. The water enter at (200-204 C) & 68.9 bar calculated the pressure drop if the flowrate 0.15 Kg/s & the power applied as a heat to the fluid is 100KW using the homogeneous model. Given that enthalpy at inlet temp.=0.87MJ/Kg, enthalpy saturation temp (285C)=1.26 MJ/Kg and μl=0.972*10-4 Ns/m2, μG=2.89*10-5 Ns/m2, UG=2.515*10-2m3/Kg and the change in UG over range of pressure=-4.45*10-4m3/Kg/bar.
4. An experimental test rig is used to examine two-phase flow regimes in horizontal pipelines. A particular experiment involved uses air and water at a temperature of 25°C, which flow through a horizontal glass tube with an internal diameter of 25.4 mm and a length of 40 m. Water is admitted at a controlled rate of 0.026 kgs at one end and air at a rate of 5 x 104 kgs in the same direction. The density of water is 1000 kgm³, and the density of air is 1.2 kgm. Determine the mass flow rate, the mean density, gas void fraction, and the superficial velocities of the air and water. Answer: 0.02605 kgs 1, 61.1 kgm³, 0.94, 0.822 ms-1, 0.051 ms-1
