Chapter 7, Problem 7.19P
Interpretation Introduction

(a)

Interpretation:

The given item of information which suggests that the chamber may be considered adiabatic is to be predicted.

Concept introduction:

The thermocouple potentiometer consists of two metals. These metals are joined together at different temperatures and forms two junctions. It measures the amount of voltage flowing through the circuit.

Interpretation Introduction

(b)

Interpretation:

The energy balance for the gas in the chamber is to be predicted. The value of U^(J/mol) at each of the observed temperatures is to be calculated. The solution is to be expressed as a table of U^ versus T.

Concept introduction:

The thermocouple potentiometer consists of two metals. These metals are joined together at different temperatures and forms two junctions. It measures the amount of voltage flowing through the circuit.

Interpretation Introduction

(c)

Interpretation:

The purpose of the stirrer is to be stated.

Concept introduction:

The thermocouple potentiometer consists of two metals. These metals are joined together at different temperatures and forms two junctions. It measures the amount of voltage flowing through the circuit.

Interpretation Introduction

(d)

Interpretation:

The fate of 0.14W of power that does not go to raise the temperature of the gas is to be predicted.

Concept introduction:

The resistance is a physical property of a conductor. It resists the flow of current. There is an inverse relationship between the resistance and the current. Higher the value of a resistance, lower is the value of current. Current and power are directly proportional to each other. Lower the value of current, the lower is the power given by the battery.

Interpretation Introduction

(e)

Interpretation:

The statement that the calculated values of U does not precisely correspond to the values at the calculated temperatures and 1 atm is to be justified and basis of the justification is to be stated. The several ways to provide the quantitative validation of the statement are to be suggested.

Concept introduction:

The ideal gas law of a gas is represented by the formula,

PV=nRT

Here,

  • P is pressure.
  • R is gas constant.
  • V is volume.
  • T is temperature.
  • n is the number of moles of a gas.

Advance Statistics and DOL 01 (90%): Use the below experimental regions information and the data given in the below table to run and analyze the Yield of reactor presented below: Factors; Response: Temperature (°C): (150, 250) Pressure (bar): (1.5, 10) Flow Rate (L/min): (10, 30) Yield (%): Hypothetical yield data for each combination of factors. Use 2 factorial, full factorial, Central Composite, and Box-Behnken designs to construct the design tables that are required to run the experiments (real and coded). Then analyze the results using MINITAB software to show the regression model for you think is the Yield and most effective parameters and interaction. Which design do the giving best model fitting based on your results? (Note; use 3 center point). 02 (10%): Use the Hypothetical yield data shown in the below Table to find the variance and standard deviation and the median.

Q2] The reaction AR + S is irreversible and first order. It is conducted in a PFR with 50 tubes, each with 0.5 in diameter and 1.0 m of height. 200 kg/h of reactant A (MW-80 g/gmol) with 30% inert is introduced at a pressure of 50 atm at 500°C. The output conversion is 80%. Calculate the average residence time.
