Minutes from 09/19/2000 meeting at FSU (all):

Talked about old design from last years design team

-already being built

-machinist says that he can handle any problems that may arise

-if we are really interest in doing that particular project from year we could do it over

on paper and come up with a new design; however, it would not be implemented.

-another alternative is to come up with a piece that could attach to the last years

design

-another alternative is to work on a totally separate project designing a heat transfer

device

Decided to do the heat exchanger.

-Question asked by Ivan Lee: Are we to design the heat exchanger on paper and build

it as well?

-Answer by Dr. Thistle: He has a machinist who could build it; however, if we were

interested in doing so, we maybe able to build it ourselves.

Reason for the need of a heat exchanger

-the water in the system kept heating up, which made errors appear in the experiments

-variation of temperature ranged from the normal environment to about 75-80 degrees

-insulation does not seem to work

the pumps used to move the water through system are actually under the apparatus

-the pumps act like fountain pumps and operate at 1hp-in²

Some solutions to problem

-placing heat exchanger in the reservoir

-placing the heat exchanger on a pipe and cooling or heating water using conduction

-replace a section of the pipe with stainless steel coated with an apoxy to prevent

erosion

Other questions

-Question: Do we want to have something built onto current device or something that

can just be added on?

-Answer: Basically have to go and look at actual device

-Question: What is the purpose of the head tank?

-Answer: Water from the pump has to be conditioned to flow into the flume (part that

contains live animals), so that the water can be moved into the flume at an even flow

without turbulence.

*NOTE: Meeting at the Marine Lab on 9-24-2000 at 9:30 a.m.*

Minutes from 09/24/2000 meeting at the Marine Lab (all):

Took measurements of all parts of apparatus
Requirements

-Everything must be able to be used with sea water -Keep the use of metal o a minimum

-If metal is used, it must non-reactive

Easy to disassemble for mobility
Cost (make as minimal, but a good reasonable price)
Would like I to be complete at least by April 2001
Additional information

-1 hp pump with motor at 3450 rpm

-4 pumps in series

-sketches and pictures included

Minutes from 10/09/2000 meeting at COE (group members):

New group member Wail Fadhil (not at meeting)
All messages and any other communications with Dr. Thistle/staff are to be forwarded to all group members
Arnett is Communications Liaison
Gather information about aqua-culture on web (patents, already created cooling devices)
Arnett is doing first set of calculations
Some Questions to ask Dr. Thistle

-What do you think about specifications and design concepts?

-What specific kind of device do you want?

-When is a good time to have some one run an experiment and measure the temperature

change of the water and the time it takes for the water to heat up?

-Do we get gas reimbursement or transportation?

-What type of safety design would you like?

-Any different applications that you may want to add?

Every group member make a detailed account of there schedule for the next two weeks and give to Takenya by Wednesday, 10-11-2000

NOTE: Talk with Dr. Buzyna about pumps*

Minutes from 10/18/2000 meeting at COE (group members):

*Accomplishments for past/present two months*

Finish all calculations
Visit Marine Lab
Meet with Dr. Thistle
Find out more about different materials
Create apparatus in Pro-E
Get specifications approval
Decide on components
Buy parts
Assemble
Create Specs. List
Access clients requirements
Generate midpoint review
Presentations
Completion of all deliverables
Meet with machinist
Decide on document system

Minutes from 11/07/2000 meeting at FSU (all and machinist):

Each group member went over there calculations
Machinist came up with an idea of using a chiller

-need to find out what material can be used

-Find a type of chiller that has fluid flowing through it

Ivan’s idea seems to be the best except creating a water jacket would be a challenge

-Needs to find out the coefficient of the PVC currently used in the flume

Machinist arrives

-Dave Oliff

-doliff@ocean.fsu.edu

Dave really doesn’t see where Ivan’s idea would fit in the room with the flume
Ideas about PET (polyethylene) piping
Arnett shared a new concept
Arnett’s old idea would need to use dionized water
Takenya has new idea
Pumps

-Sherwood manufactured

-Norel plastic on outside of pump

-Can not be moved at all (Idea #3 that Takenya was working on can not be used)

-1 can move about 60 gallons/min

Needs

-Measurement of water temperature coming out of the head tank

Last comments

-Dr. Thistle likes machinist idea

-Need to look at chillers

-Collect temperature data

-At next meeting have some practical data and information

-Assume the max. (all four pumps working at the same time)

-Get in contact with Keith Sutherland
