Team Roles

• Chris Kulbago- Project Manager• James Brinkerhoff- Lead Engineer• Lauren Pahls- Fluids Specialist• Sarah Salmon- Group Facilitator• Patrick O’Connell- Lead Mechanical• Ted Rakiewicz- Lead Electrical

Project Background• TaskPractically demonstrate process control in a lab environment using a gravity fed loop with a control valve. • CustomerRIT’s Chemical Engineering Department• Product StakeholdersStudents who will use the machine, the Department, Dr. Sanchez, Dr. Richter, and staff who will maintain the machine.• CollaborationTwo other groups are designing similar process control machines whose aesthetic appearances must match ours.

3 Week Look Ahead

5

Customer Needs• Machine Design Needs:

An easily transportable/cleaned cart.A somewhat easy to disassemble cart.A way for students to manually manipulate flow A way for students to manipulate flow through LabVIEW.A way to manually measure flow. A way to measure flow through LabVIEW.Easily operated by 3 students.A safely operating machine.Interface of machine with LabVIEW.A way to demonstrate each part of the PID equation.A way to demonstrate noise in sensors. A way to demonstrate the time lag. Minimal use of water and electricity.

6

Customer Needs• Student Learning Needs:

A lab manual that guides students through lab in a way that engenders learning. Questions for the post lab report that test student's understanding of process control. Lab manual that focuses on PID, noise, filtration, data modeling, disturbances, and/or hysteresis.

Engineering Specifications

Feasibility Analysis• Line pressure confirmation• With one faucet received around 50 psi• With all faucets on decreased to about 45 psi

9

Feasibility: Fluids Analysis• Initial Analysis using Bernoulli’s Equation• Assumptions:• Neglecting Line Losses• Calculated for when the elevated holding tank is about to be

empty. • Desired flow rate = 1000 g/min. • Fluid = Water; Density = 1E6 g/m3. • Plastic Tubing with I.D. = 3/8 in. • Plane 1 = Tank Outlet and Plane 2 = Valve Inlet• Velocity @ 1 = 0 m/s, and Pressure @ 1 = Atmospheric• Height @ 2 = 0 m, and Pressure @ 2 = 40 psi = 275 kPa

Risk Assessment

25

Test Plan Summary• Test flow rates• Simulate control valves in ChemCAD• Demonstrate PID control flows• LabVIEW interface functionality• Confirm ferrule ratings• Microcontroller testing• Lab maintenance update for spills

26

Issues/Actions• Gravity fed to line fed• We initially were going to have a project that was “gravity fed,”

where we had a permanent height for a gravity feed stream• Instead of this, we decided to use a second control valve and set

of code in order to be able to be more versatile and mimic different heights with different water pressures from a water line

• Coordinating cart purchase• We have had a slight issue coming up with a cart idea that works

for the three groups.• After negotiating, we have come up with a final cart

• Slow start to project• Edge was not readily available for students at the start of MSD I• The lab learning portion is in progress 27

Cart Choice

The cart of choice is a QuantumStorage Systems 32.5 inchUtility CartThe cart has a depth onthe top shelf of 17.5inches, and is composedof plasticIndustrial strength cartCart comes with 1-yearlimited warranty

28

Next Steps• Final budget approval from Chemical Engineering Department• Purchase 3 carts, one for each group• Place purchase orders for all high lead time items• Patrick & Lauren to monitor materials received over summer• Simulate heights and create models in ChemCAD• Confirm donations from our department and Kodak• Procure and document all donations
