## FLUID MECHANICS

### THEORY

The theory includes conservation of mass, momentum and energy, static and stagnation property relations, Moody chart roughness and Bernoulli’s principle.

### LECTURER’S EXAMPLE TO SHOW IN CLASS

The Flownex®SE network with graphical interface dynamically illustrates the effect of pipe roughness and flow velocity on the energy and hydraulic grade line. The example uses a short pipeline section with an elevation difference between the inlet and outlet (that holds pitot tubes and stand pipes) that indicates the pressure difference.

### STUDENT PROJECT TO USE AS ASSIGNMENT

A student assignment with results memorandum evaluates the knowledge and understanding of the students using either hand calculations or Flownex® as software tool. The assignment expects the student to calculate the flow through a flow meter using specified pressure readings from the instrumentation.

## HEAT TRANSFER

### THEORY

Theory includes conservation of energy as well as one-dimensional steady-state conduction relations through a plane wall and cylindrical pipe geometries.

### LECTURER’S EXAMPLE TO SHOW IN CLASS

The Flownex® SE network with graphical interface dynamically illustrates the difference between plane wall and cylindrical wall heat transfer with varying wall thickness. The example uses a heat transfer element and pipe combination which either model a tube or plane wall with water flowing on the one side and air over the other. ### STUDENT PROJECT TO USE AS ASSIGNMENT

A student assignment with results memorandum evaluates the knowledge and understanding of the students using either hand calculations or Flownex® as software tool. The exercise expects the student to calculate and compare the air side wall surface temperature of both the plane wall and tube scenarios using the same specified wall thickness.

## THERMODYNAMICS

### THEORY

The theory includes first law of thermodynamics, fluid property diagrams, ideal gas law relations and the Joule-Thomson coefficient.

### LECTURER’S EXAMPLE TO SHOW IN CLASS

The Flownex® SE network with graphical interface dynamically illustrates the effect of varying throttling and system temperatures on pressure-temperature relations of fluids. The example uses a pressurized tank blowing off to another reservoir through a short pipeline with a restrictor. Helium, Nitrogen and air are used as fluids. ### STUDENT PROJECT TO USE AS ASSIGNMENT

A student assignment with results memorandum evaluates the knowledge and understanding of the students using either hand calculations or Flownex® as software tool. The exercise expects the student to calculate the pressures and temperatures of a basic heat pump system using a pump, valve and specified heat transfer requirement.
