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,
Ts,), 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 its 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).
