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 • Task Practically demonstrate process control in a lab environment using a gravity fed loop with a control valve. • Customer RIT’s Chemical Engineering Department • Product Stakeholders Students who will use the machine, the Department, Dr. Sanchez, Dr. Richter, and staff who will maintain the machine. • Collaboration Two other groups are designing similar process control machines whose aesthetic appearances must match ours.
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.
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.
Feasibility Analysis • Line pressure confirmation • With one faucet received around 50 psi • With all faucets on decreased to about 45 psi
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
Bill of Materials Key notes: Budget total $1256.57 Assuming no sales tax for educational activities Will confirm Kindorf Bracketing with Paul
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
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
Cart Choice The cart of choice is a QuantumStorage Systems 32.5 inchUtility Cart The cart has a depth onthe top shelf of 17.5inches, and is composedof plastic Industrial strength cart Cart comes with 1-yearlimited warranty
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
