(a)

Interpretation Introduction

Interpretation:

Temperature difference across wall is to be determined.

Concept Introduction:

The fundamental concept of steady state conduction is used to determine the temperature drop. Temperature drop across the wall depends on the ratio of overall thermal resistance and wall resistance as well as inner and outer fluid temperatures.

(b)

Interpretation Introduction

Interpretation:

Polymer deposit thickness is to be determined.

Concept Introduction:

Substance thickness depends on product of thermal resistance offered by the substance and its thermal conductivity. Furthermore, thermal resistance offered by the substance depends not only on the overall temperature difference but also the temperature-drop across wall.

(c)

Interpretation Introduction

Interpretation:

Rise in the magnitude of heat flux is to be determined.

Concept Introduction:

Magnitude of heat flux is actually inversely proportional to the ratio of overall thermal resistances between the previous and modified design. This means that the factors to consider are thermal resistance of previous design as calculated in sub-part (a) and a new overall composite thermal resistance that includes the effect of new layer and shell thickness along with the thermal conductivities of materials in question.

chemical engineering Material-energy balance.   Only focus on the nitrogen gas, which is H(3)
1. The settling chamber, shown schematically in Figure 2E1.1, is used as a primary separation device in the removal of dust particles of density 1500 kg/m³ from a gas of density 0:7 kg/m³ and viscosity 1.90 x 10-5 Pa s. Gas inlet Elevation Gas Gas exit exit H Collection surface -W Section X-X Dimensions: H=3m L = 10 m W=2m Figure 2E1.1 Schematic diagram of settling chamber Assuming Stokes' law applies, show that the efficiency of collection of particles of size x is given by the expression collection efficiency, x = x²8(pp - Pi)L 18μHU where U is the uniform gas velocity through the parallel-sided section of the chamber. State any other assumptions made. (b) What is the upper limit of particle size for which Stokes' law applies? (c) When the volumetric flow rate of gas is 0.9 m³/s, and the dimensions of the chamber are those shown in Figure 2E1.1, determine the collection efficiency for spherical particles of diameter 30 mm.
Can you answer this sequantially correct like show me the full process. Also, since it is chemical engineering related problem a perry's handbook is used. Thank you
