Problem Solving Examinations Example: Students will calculate the available water supply and required fire flow for a 100,000 square foot warehouse. Grade based on industry standard. Reports Example: In a report, students will explain the effect of elevation on the ability of a pump to obtain a vacuum and obtain a maximum lift. Rubric Grading. Repeatable No Methods of Instruction Lecture/Discussion Distance Learning Lecture: The instructor will lecture on fire suppression sprinkler systems. The students will then be provided diagrams and schematics of a sprinkler system and will have to identify all components of the system. (Objective 24) The instructor will lecture on the correct procedure of obtaining pressure readings for fire hydrant flow tests. The students will then perform field mathematical calculations to determine the water flow from various hydrants. Distance Learning Students will be required respond to weekly instructor questions and post responses. Students will also be required to respond to other student posts pertaining to the instructor questions. Example question: What is the difference between velocity and flow? Typical Out of Class Assignments Reading Assignments 1. The student will read the material in the textbook on Bernoulli's theorem and and be prepared to discuss in class how Bernoulli's equation and Torricelli's equation are inter-related. 2. The student will read the chapter on pump theory in the textbook and then complete the provided work sheet showing the water flow through a single stage pump and a dual stage pump in both the series and parallel setting. Writing, Problem Solving or Performance 1. Prepare a list comparing and contrasting positive displacement pumps, rotary vane pumps, rotary lobe pumps, axial flow pumps, and radial flow pumps. 2. Weekly homework exercises utilizing specific formulas to solve various water flow problems.
