Once the data is collected, the students analyze the measurements and calculate flow rates, velocities, and pressure drops. They compare the results obtained from different flow meters and evaluate their accuracy and precision. The students also assess the uncertainties associated with the measurements and discuss possible sources of error. Finally, they interpret the data in the context of fluid flow principles and draw conclusions from their findings.
Experiment 2: Heat Transfer Analysis
The second experiment in CE 427LLB focuses on heat transfer analysis. Heat transfer is a critical aspect of chemical engineering processes, and understanding its principles is essential for designing efficient heat exchangers, reactors, and other heat transfer equipment. The experiment involves the following steps:
Purpose of the experiment
The purpose of the heat transfer analysis experiment is to investigate heat transfer mechanisms, such as conduction, convection, and radiation. Students learn how to measure and analyze heat transfer rates and coefficients in different scenarios, such as steady-state and transient heat conduction, forced and natural convection, and thermal radiation.
Apparatus and setup
The experiment setup includes a heat transfer unit with various surfaces, insulation materials, temperature sensors, and heat sources. The students can control the heat input and measure temperature gradients at different locations using thermocouples or resistance temperature detectors (RTDs). They also utilize a data acquisition system to record temperature data over time.
Procedure and observations
The students begin by setting up the heat transfer unit and configuring it for the specific experiment. They carefully place the temperature sensors at strategic positions to capture temperature variations accurately. The students then apply the necessary heat input and monitor the temperature changes over a specified period. They record the data at regular intervals and make observations regarding heat distribution and transfer mechanisms.
Data analysis and interpretation
After collecting the temperature data, the students analyze it to determine heat transfer rates, temperature gradients, and coefficients. They apply relevant heat transfer equations and principles to calculate heat conduction, convective heat transfer coefficients, or radiative heat transfer rates. The students interpret the data to understand the efficiency of heat transfer in different scenarios and discuss the factors that affect heat transfer performance.
Experiment 3: Reaction Kinetics
The third experiment in CE 427LLB focuses on reaction kinetics, a crucial aspect of chemical engineering that involves studying the rates at which chemical reactions occur. Understanding reaction kinetics helps in optimizing reaction conditions, designing reactors, and predicting product yields. The experiment involves the following steps:
Purpose of the experiment
The purpose of the reaction kinetics experiment is to investigate the rate of a chemical reaction and understand the factors influencing it. Students learn how to measure reaction rates, determine reaction orders, and analyze reaction mechanisms. They also explore the effect of temperature and catalysts on reaction rates.
Apparatus and setup
The experiment requires a reaction vessel, temperature control system, reagents, and appropriate instrumentation for measuring reaction progress. The reaction vessel is equipped with temperature sensors, stirrers, and probes for monitoring reactant concentrations.
Procedure and observations
The students begin by preparing the reaction mixture according to the experimental design. They carefully control the temperature and initiate the reaction by adding the necessary reagents. Throughout the course of the experiment, the students monitor the reaction progress by measuring changes in temperature, reactant concentrations, or other relevant parameters. They record their observations at regular intervals, noting any visible changes or trends.
Data analysis and interpretation
Once the experimental data is collected, the students analyze it to determine the reaction rate, reaction order, and rate constant. They may employ mathematical models, such as the rate equation or integrated rate laws, to fit the experimental data and extract kinetic parameters. The students interpret the results in terms of reaction mechanisms and discuss the factors that influence reaction rates, such as temperature, concentration, and catalysts.
