My Instructor's user page which points to this.

My task was

 * Design new blood cooler water container using CAD.
 * measure the volume pumped per second.
 * Convert the volume to mass using math conversions.

What I did

 * Used AutoCAD to design the elbow using you-tube video. Here is the link to the video. https://www.youtube.com/watch?v=_kuo52_KoX4
 * Made a water container and base using CAD.
 * Constrain the elbow and the water container together.
 * Measured the time it takes the water pump to fill a 25ml graduate cylinder. Took several trial then took the average. It takes 5sec to fill the 25ml cylinder.
 * Convert the milliliter to gram then to kg. so that be able to put in the heat formula which is:- Heat=mass(change in temp)(constant heat of latent)(time)
 * Used the mass and ml relation which is 1ml=1gm so 25ml=25gm.
 * Change the 25gm/5sec to kg/sec which is 0.005kg/s
 * To prove that the relation it true. Measured the 25ml on a digital weight it approximate came 24.903 which is roughly 25ml.

Proposed next steps

 * Brainstorm weather to create a circuit inside the water container that connect to the blood cooler or drill out holes.
 * find the temperature change before the water leaves and the temperature of water container and after it comeback.
 * Design a CAD drawing with the blood cooler placed.

My task was

 * find the time needed to drop core temp of body.
 * Measure water pump volume/sec
 * Measure temperature of ice water.
 * Find the temperature after a work out.

What I did

 * Attempted three trials to measure the the water pump volume per second
 * First trial resulted with 25ml/4.71sec. here is the link to the demonstration http://youtu.be/gMKvxZ9XKsc
 * Second trial resulted with 25ml/4.76sec Link to second trial demonstration http://youtu.be/2EfTghHH-cI
 * Third trial resulted with 25ml/5.3sec linlk to third trial demonstration http://youtu.be/sfoqg9jBYGQ
 * Took the average time, it comes to be around 4.9sec.
 * When putted in kg/sec it becomes 0.005kg/sec
 * Found that a normal core temperature of the body ranges from 97.7 degress to 99.5 degree Fahrenheit. During exercise our core temperature can reach above 104 degree Fahrenheit. link to the source http://healthyliving.azcentral.com/body-temperature-elevated-after-long-workout-19694.html

Proposed next steps

 * Measure the temperature of the ice water.
 * Use the physics calculation and find the time needed to drop core temperature of body.
 * Add the result to presentation page.
 * Work on the presentation on Thursday.

My task was

 * Measure the temperature of ice water.
 * Prepare for presentation on Thursday at the Kettle man hall.
 * Calculate the the heat that is released by the water.

What I did

 * Used a thermometer to measure the temperature of the ice water. The temperature of the ice water was 0 degree Celsius. More about the temperature of ice water go to the link https://en.wikipedia.org/wiki/Ice
 * The formula to find the amount of heat absorbed or released is found by multiplying the(( Δ T) is the temperature difference X (c)is the specific heat of the body X (m) is the mass of the body) to see more go to http://formulas.tutorvista.com/physics/temperature-formula.html


 * specific heat capacity of water is 0.0042 j/kgc.
 * Presented about the purpose of blood cooler and also demonstrated it working.

Proposed next steps

 * solve the equations for the heat released by the body.
 * Find the Q of water.
 * Find the temperature of the return water.
 * find the heat released by the body during exercise

My task was

 * Find the heat released by a body during exercise.
 * Find the temperature of the water that comes back to water container.
 * find the time needed to drop core temp of body.

What I did
http://www.physlink.com/Education/AskExperts/ae420.cfm
 * For a normal healthy person at regular day body temperature is 37 degree Celsius. Found more interesting facts about our body temperature on this website http://www.webmd.com/first-aid/body-temperature.
 * The heat energy that a person produces is a range of 70-870 watts, with 70 watts being a resting state
 * In a resting state the body release 70j/s.

Proposed next steps

 * calculate the time needed to drop the core temperature of a body.

My task was

 * Take the blood cooler to HCC gym and ask a volunteers to try it.
 * Measure the ice water temperature
 * measure the temperature of the return water.
 * Ask volunteers for any suggestions.
 * Post videos of the whole process.

What I did

 * Took the blood cooler to HCC Gym and asked people if they want to try the blood cooler. found one volunteer who is willing to try the blood cooler.
 * Measured the ice water temperate and the return water.


 * Change in temperature was 2 degree Celsius.
 * Before the use of the blood cooler the volunteer was able to do four press with extreme challenge. here is a video showing that.http://youtu.be/DnN_EeIJd1Y
 * Here is a video while using the blood control. http://youtu.be/c5oX1uCFhP0
 * After the use of the core control volunteer was able to perform better and gave a positive comment.http://youtu.be/58UCW3ge5Ug
 * second trial with different exercise.
 * Before the use of core control volunteer was only able to do 11 press. Some footage was cutted due to technical problems. http://youtu.be/GeY3uT0bEG4
 * Used the blood control to enhance performance. http://youtu.be/KFqNmW5QuEo
 * After the use of the blood cooler the volunteer was able to do three more press than the previous one and was not as challenging as it was.http://youtu.be/eXn0VPM3keM
 * comment http://youtu.be/2_BOA8G0fzw

Proposed next steps

 * Get more volunteers to test it out.
 * Shoot a good video of the blood cooler working.
 * Install the blood cooler at the HCC Gym.

My task was

 * capture red face while working out to show the core temperature rise.
 * Measure Ice water temperature before and after
 * Measure the temperature of ice water that just get heat from the air.
 * Measure the temperature of ice water that went through the blood cooler.

What i did

 * During the past week several trials have been done at the hcc gym. The testes were conducted at the same room temperature,(25 degrees centigrade).
 * The experiment involved the a bunch of ice that are to used on the experiment.
 * The first step was to measure the temperature of the ice water. The ice water was measured using a thermometer and it show that the ice water is 0 degree Celsius. For further research for the temperature ice water go to https://en.wikipedia.org/wiki/Ice.
 * Next step was to measure the temperature of the ice water that just get heat from the air. To do this, used a cup filled with ice water and left it out in the open for five minutes the temperature was measured to be 7 Degree Celsius.


 * The third step was to setup the blood cooler and ask any volunteers to try the blood.
 * Before the volunteer tries the blood cooler, he needs to raise his core temperature, so he worked out for a while and got exhausted. To see whether the core temperature was raised,his red face was captured.
 * Here is a link showing all the process. http://youtu.be/Lky10aeExfc.
 * To find the temperature of the ice water that went through the blood cooler,
 * While the hand of volunteer was still garbing the brass rod inside the blood cooler, the temperature of water going through the blood cooler was measured. https://www.youtube.com/watch?v=N2QgIc8BULI&list=UUFQpzIaGRN-wt7oGY9HmOXw.
 * The temperature was measured as 7 degree Celsius.
 * Using the formula of heat Q=mcdt to figure out the heat released by the water.
 * specific heat Of water is 4181j/kgc http://www.bbc.co.uk/schools/gcsebitesize/science/aqa/heatingandcooling/buildingsrev3.shtml


 * THE heat released by the body is 350000/hr or 5833.33j/sec.http://www.physlink.com/Education/AskExperts/ae420.cfm

problems faced during this experiment

 * During these experiment people were struggling to put on and off the cones.
 * The length of the tubes was short.
 * The water pump was liking.
 * The cones were leaving marks at users arm.

Proposed next steps

 * Find the time needed to drop the body core temperature.
 * Do more trials.
 * Design more comfortable cones, and ease to use.
 * Fix the water pump from liking.
