ΔT

Introduction

Cash prizes worth 16000 INR to be won!

Finals - 26^th February, 1100 hrs to 1700 hrs, CEESAT

Here is an event that calls for you to build a contraption to heat water from room temperature and raise it to a height of 1.5 metres. Sounds simple enough. But wait, there’s a catch… No electrically dependent heating techniques, or the use of fire. Intriguing? In ΔT, you are invited to add a whole new dimension to the ancient art of heating water. Come up with ideas as you try to gain a "delta" over your opponents in this super - hot event!

It could be an exothermic reaction with a piece of your intellect, so it's better than what a chemical can serve; or even a heating unit adding internal energy to water.

Well, sort it out.... It means a lot of cash!

Registrations are now closed.

The last date of registrations is 16th February and the last date for the submission of abstracts is 20th February.

Internships at SRF for the top finishers at ΔT 2010!

Problem Statement

Heat water without using fire or electricity and raise it to the height of 1.5 metres. The final state SHOULD be water and NOT vapor.

Participants are required to submit a brief write-up of their prototype giving the specifications and materials used for making the model. Use the registration form to upload your synopsis.

Shortlisting for the on campus finals will be done based on the synopsis.

Shortlisted teams will be intimated at the earliest through email.

Rules and Regulations

Team Specifications

A team may consist of a maximum of three members.

Setup Specifications

No electrical energy input is permitted.
The dimensions of the equipment used in the setup are to be decided by the teams.
Design must however make room within a floor area of 100cm X 100cm. No part of the setup should project outside this limit.

Rules

Teams will be given ordinary tap water. They will have to heat it to the maximum possible temperature and raise it to a height of 1.5 metres in minimum time.
The height of water raised will be measured from base of the vessel in which the water is taken initially to the base of the vessel in which the water is collected finally at the end of the time limit provided.
Time allotted for heating and elevating is 10 minutes.
No external materials (eg: funnel etc) will be provided.
Mechanical methods of supplying work are allowed for heating.
The model should be made in the area of 1m x 1m and no part of it should project outside 1m x 1m.
It does not matter if the elevation of water takes place before, during or after heating.
Human interruptions are allowed in the process, but one cannot manually take water from the container at ground and put it in the container at the top.
Boiling water contains bonus marks, but the team must ensure to condense all the water it has vaporized.
The volume of water taken initially must not change at the end of process. It will lead to negative marking.
No substance should be added to the water given. It may lead to disqualification if the added substance is not removed finally.
If any team wants to finish in time less than 10 minutes, they are permitted to do so but this will not affect their score.
The heated liquid must be collected in a separate container which should be preferably brought by the participants.
The temperature of water in the collecting container will be measured at the end of 10 minutes.
The organizers reserve the rights to change any of the above rules as they deem fit. Changes in rules, if any, will be highlighted on the website and registered participants will be notified.

Judging Criteria:

Marking will be done on the following basis:

Temperature difference attained.
Volume of water heated and elevated.
Time taken for elevation.
Portability of the model.
Application.

Marking scheme:

Formula: 0

V: Volume of water used (liters)
T: Temperature difference attained (°C)
t: Time taken to raise the water up to the given height (minutes)
f: Marks given by the judge on portability, application, overall concept and idea used out of 10.
S: Final score

If any volume is lost in the process, then the marks will be reduced from the score S. The percentage of marks reduced will be equal to the percentage of volume lost.

If any part of model projects out of the provided 1m x 1m then 2% of score S will be reduced per cm. 5% of the score 'S' will be added to the total score if the water boils.

FAQ

How will the portability and the application of the model be judged?
We will be having a professor from our college to judge the participants on these criteria. His/her decision will be final in this regard.
What all items will be provided by the organizers?
The organizers will be providing the following things:
1. The exact volume of water that the participants will be requiring.
2. The container to store the water, if its not brought by the participating team. We may provide the container both on the ground level and at the height of 1.5 m. But the design of the container is at the discretion of the organizers, so its advisable for the participants to bring their own containers.
3. A flat surface at the height of 1.5 m so that the participants can store the hot water collected in their container.
4. A thermometer to measure the temperature of water.
What about solar energy? Can I use it?
Yes, you can use it at your own risk. The organizers will not be held responsible if the nature does not favour you on that day. If its cloudy, your model might not work.
How will my marks be affected if I add something to the water to heat it?
Addition of a substance would not affect your score provided you are successful enough to remove the substance within the given time.
