Nano-scale Phase Change Materials (PCM’s) and Their Effect on Heat Transfer Fluids Sean Schulte‚ Chaoming Wang‚ Ming Su 1NanoScience Technology Center‚ 2Department of Mechanical‚ Materials‚ and Aerospace Engineering‚ University of Central Florida‚ Orlando‚ Florida 32826. mingsu@mail.ucf.edu Abstract: Introduction: Heat transfer fluids (HTF’s) are often used as carriers in heat transfer equipment. It therefor comes as no surprise that finding a way to make HTF’s more efficient is desirable

ADVANCED LABORATORY I FALL‚ 2000 ADIABATIC CALORIMETRY Reference: S‚G‚&N Exp. 8 in Chp. VI. Objectives: (1) Determine the integral heat of solution for finite amounts of KNO3 dissolved in water. Extrapolate the measurement to infinite dilution to obtain the differential heat of dilution. (2) Incorporate the concepts learned in your Electronics laboratory to amplify and accurately measure temperature changes associated with solution formation. (3) Use the A/D capabilities of a computer to record voltage

The first law of thermodynamics says that energy cannot be created or destroyed. In this lab we measured the energy given off in the form of heat to determine other experimental values. We know that heat can be transferred from one object to another in predictable ways. For

Eames suggested Captain Smith letting Titanic go with the full speed. And what they did in the film is asking the workers to add more coals to run the machines‚ which I believe are diesel engine or steam engine. According to the first law of Thermodynamics we learned in Chapter 15‚ we knew that internal energy equals heat minus work done by the engine. (ΔU=Q-Wby) The work done by the engines made Titanic go forward. This is an energy transfer from heat to mechanic energy. And because the efficiency

An intensive property is a bulk property‚ meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system. Examples of intensive properties are the temperature and the hardness of an object. No matter how small a diamond is cut‚ it maintains its intrinsic hardness. By contrast‚ an extensive property is one that is additive for independent‚ noninteracting subsystems.[1] The property is proportional to the amount of material in the

Forces What Is a Force? Forces represent the interaction of distinguishable objects. Specific forces: The weight W with magnitude W = m * g acts near Earth’s surface with g the gravitational acceleration. (m= mass) The normal force N is due to contact with a surface. It is directed perpendicular to the surface. The tension T is due to a taut‚ massless string. It is directed along the string. The external contact force Fext acts along the direction of the push. Unit: Force and force

ENERGY RESERVES OF MACROMOLECULES SUMMARY This experiment was conducted in order to show the energy received from the food that humans eat on a daily basis. The energy that is required by the human body to perform chemical reactions is obtained from the chemical bonds that formed between the atoms in the molecules. To calculate the amount energy‚ types of food products were burned underneath a test-tube filled with water. The temperature rise gave an estimate of the energy released per gram.

to do such and they have a much higher energy because of it. I also found that surface tension is measured in forces per unit length and stated in newton’s per meter but it can also be measured as joules per square meter if it is in the use of thermodynamics where it is expressed as work done per unit of area where it is stored as potential energy which is the energy that a piece of matter has because of its position or because of its arrangement of parts. Water molecules that are at the surface
