DELIVERABLE #1 DUE ON TUE

9/26 (Project Scope)

The Project Scope document is due on Tue. 9/26 at 4PM (end of lecture)

The document is due in paper format. Extra credit for documents fully

submitted in electronic format via the Course info Digital Drop box. A copy

should also be given to your Sponsor!!!

This should be a self-contained document presenting the scope of the

design project as agreed between the team and the sponsor. There is no

page limit (minimum or maximum). The document should be as complete

as possible in terms of what is the problem to be solved, what is the

background for it, and what the sponsor expects in terms of completed

work. However, a good project scope should be crisp and to the point (no

lengthy explanations or excessive detail are needed).

Our project has changed from our original charge. Originally we were to design an isokenetic flow sampler for the Marine Research facility at Alligator point. This project has reached a level of completion, to which we would not effectively contribute to ongoing research. Instead we have been charged with designing a heat exchanger for an experimental setup up in the facility.
 

Background:
 

The experimental setup we are working on is a coastline simulator. The system has a trough, through which, a steady flow can be used to measure and record the actions of organisms as they move through sediments. This system is open (to observe behavior) to a room maintained throughout the year at 72 degrees F. This system has a constant flow generated by a honeycomb system to reduce velocity gradients. A large head tank provides the supply of water. Four, 1 hp industrial pumps maintain its level. These draw the water into the tank from a reservoir tank at the end of the trough.

During the winter and early spring, the researchers using the condition simulator notice that the water temperature had dramatically changed during an hour and a half period. This change was from 50 degrees F to almost 75 degrees F.
 

What we have to accomplish:
 

We must design a system or find an available product that will be easily incorporated into the simulator. The design or product we come up with should be able to fit easily with existing parts. I must be competitively priced, if building such a device would be time prohibitive (it must be online as soon as possible). The new part of this system must be able to withstand a harsh seawater environment for an acceptable period of time. Because of the live animal experiments, whatever materials are used must be environmentally neutral. As part of this design, this unit would have to be able to maintain the water temperature (thermostat controlled) when all four pumps are running. We will have to consult with civil and electrical faculty and students on wiring design, and effective mounting of the system if we must place the unit on a wall. It must obviously comply with all safety codes to be an effective design. Due to the unknown status, of whether or not FSU would be forced to move the facility, it must be able to be moved and setup with the system if such a move became fact.
 

Calculations/Experiments, and data to be collected:
 

We must perform a run with the system at full capacity to find the temperature change with respect to time

The total heat flux into the system from the room

Find design data on the simulator

Test to see if reconditioning of the pumps was not effective causing heat buildup

Preliminary searches for marine cooling system or patents online

Calculations to see how much and how quickly water must be drawn off and cooled in order to maintain temperatures at full operation

Calculations to see what flow would be best (laminar, turbulent, or degrees of) to best mix water while minimizing head loss

Design meetings to determine the best place (reservoir, at the pumps, the head tank) to draw water from and to put water back into the system
