A Batch Distillation Process

A Batch Distillation Process Chemical and environmental engineers must sometimes design batch processes for producing or purifying liquids and gases. Applications of such processes occur in food and medicine production, and in waste processing and water purification. An example of such a process is a system for heating a liquid benzene/toluene solution to distill a pure benzene vapor. A…

An Environmental Database

An Environmental Database Data collection is important for early detection of changes in our environment. In order to detect such changes, we need to be able to analyze the database efficiently, and this effort requires a database that is set up for easy access. As a simple example, suppose you want to create a 2 x 2 cell…

Eearthquake-Resistant Building Design

Eearthquake-Resistant Building Design Buildings designed to withstand earthquakes must have natural frequencies of vibration that are not close to the ,oscillation frequency of the ground motion. A building’s natural frequencies are determined primarily by the masses of its floors and by the lateral stiffness of its supporting columns (which act like horizontal springs). We can find these frequencies by…

Product Cost Analysis

Product Cost Analysis shows the costs associated with a certain product, and shows the production volume for the four quarters of the business year. Use MATLAB to find the quarterly costs for materials, labor, and transportation; the total material, labor, and transportation costs for the year; and the total quarterly costs. Solution The costs are the product of…

Height versus Velocity

Height versus Velocity In introductory physics courses Iewton’s laws of motion are used to derive the following formula for the maximum height li achieved by an object thrown with a speed v at an angle B to the horizontal In introductory physics courses newton’s laws of motion are used to derive the following formula for the maximum height…

Manufacturing Cost Analysis

Manufacturing Cost Analysis Shows the hourly cost of four types of manufacturing processes. It also shows the number of hours required of each process to produce three different products. Use matrices and MATLAB to solve the following. (a) Determine the cost of each process to produce one unit of product I. (b) Determine the cost to make one…

Current and Power Dissipation in Resistors

Current and Power Dissipation in Resistors The current i passing through an electrical resistor having a voltage v across it is given by Ohm’s law: i = vIR, where R is the resistance. The P?w’er dissipated in the resistor is given “‘”‘ by v2/.R. The following table gives data for the resistance and voltage for five resistors. Use…

Transportat on Route Analysis

Transportat on Route Analysis The following table gives data for the distance traveled along five truck routes and the corresponding time required to traverse each route. Use the data to compute the average speed required to drive each route. Find the route that has the highest average speed. Solution For example, the average speed on the first…

Aortic Pressure Model

Aortic Pressure Model Biomedical engineers often design instrumentation to measure physiological processes, such as blood pressure. To do this they must develop mathematical models of the process. The following equation is a specific case of one model used to describe the blood pressure in the aorta during systole (the period following the closure of the heart’s aortic valve). The…
