1. Pressure and Fluid Flow Lesson Plan
Phil Canale, Littleton High School
Pressure and Fluid Flow Lesson Plan
Development of a Sustainable Engineering Program
ACTION PLANS
Primer: Kids using a 50 foot hill and a hose and water measure how the pressure changes with how far down the hill they bring the other end of the hose. They then go back and calculate pressure based on angular measurements taken with a transit. Each time they take a pressure measurement they also empty the hose into buckets and weigh water held vertically.
STUDENT OUTCOMES
WRITE THE LESSONS LEARNED
Goal
Learn about pressure and fluid flow. Analysis of the effect of sources of resistance (elbows, T’s,), pipe cross sectional area, pipe length, and pressure on fluid flow.
CONTEXT
Class of 15 students in greater suburbia, class size 12 – 24. Littleton High School.
BARRIERS
Money and access to water
LESSONS LEARNED
Demonstrate the safe and proper use of common hand tools, power tools, and measurement devices used in construction (transit and drill)
Calculate and describe the ability of a hydraulic system to multiply distance, multiply force, and effect directional change.
Recognize that the velocity of a liquid moving in a pipe varies inversely with changes in the cross-sectional area of the pipe.
Sources of resistance (ie. Elbows, changes in diameter) for water moving through a pipe.
Understand and calculate pressure.
Learn how to apply the Pythagorean theorum
History of water systems.
You are in the Army Corp of Engineers and you and your team has been sent into Afghanistan to supply irrigation to three villages. You must use only local materials as you are in the middle of Afghanistan and the Air Force refuses to fly you in supplies using it’s fleet of C5 Galaxy cargo planes as you insulted the Air Force Captains mother. The list of local materials is given to you in Table I. Village number 1 is 5 miles away and 2000 feet below the water supply, Village number 2 is 2 miles away and 1000 feet below the water supply, and village 3 is 7 miles away and 3000 feet below the water supply. Due to the population in each village you must split the water unevenly. The water should be split in order to support the villages equally. The population of each village is given in Table II. (Scale your project to 3” = 1 mile).
