on its own but is dragged along behind by the spindle. High contact pressure (upto 35 N/square mm)is generated between the ring and the traveller during winding, mainly due to centrifugal force. This pressure leads to generation of heat. Low mass of the traveller does not permit dissipation of the generated heat in the short time available. As a result the operating speed of the traveller is limited. Heat produced when by the ringtraveller is around 300 degree celcius. This has to be dissipated

Joseph N. Frederick III PSC 1121C Spring 2011 Geophysics Geophysics can be broken down into several groups that deal with physical science and the earth. It is a field and profession that combines geology, mathematics, and physics all in an effort for people across the world to understand the ways of the world and exactly what it takes for certain seemingly unnatural events to happen. Geophysics covers a range of ideas from gravity, heat flow, seismic waves that cause vibrations through the

Thermodynamics is a branch of physics concerned with heat and temperature and their relation to energy and work. It defines macroscopic variables, such as internal energy, entropy, and pressure, that partly describe a body of matter or radiation. It states that the behavior of those variables is subject to general constraints, that are common to all materials, not the peculiar properties of particular materials. These general constraints are expressed in the four laws of thermodynamics. Thermodynamics

fuels to produce electricity or used as a direct energy source. The use of solar energy to pre-heat water for industrial, commercial and institutional and residential purposes can reduce electricity usage by up to 2% to 6% in southern Ontario. Adding the emissions from using natural gas directly to heat water a figure of 5% to 17% reduction in CO2 emissions can be derived by the use of solar energy to pre-heat water. This report details the equipment necessary for such a domestic solar hot water system
