Vapor Pressure and Heat of Vaporization Introduction: Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside

1. Shell and Tube Heat Exchanger – Working Principle The shell and tube heat exchanger comprises of two major things as its name state "Shell and Tube". The shell is a major vassel with quantities of tube inside it (Jalmood‚ n.d). Shell and tube heat exchangers are helpful for pressurized application. Heat is exchanged between the liquid in the tubes and the liquid inside the shell. Configuration of the tube pack is such that‚ all the section sides of the tube could be joined with a typical header

Heat Transfer Phenomena in Heat Gun – Effect of Melting Heat gun is actually a one of the common power tools which usually can be found in autoshop. This particular of tool looks alike to hair dryer (that normally being used in house to drying wet hair). Heat gun is actually pretty handy tool as it can be used to desoldering electronic components‚ shrink warping and heat shrink tubing‚ bending PVC pipe and tube‚ window tinting‚ vinyl and leather repair‚ as well as many others unconventional creative

temperature distribution at a given location on the plate may be approximated as T = 30 + 70 exp ( −y ) where y (in m) is the distance normal to the plate and T is in °C. If thermal conductivity of the fluid is 1.0W/mK‚ the local convective heat transfer coefficient (in W/m2K) at that location will be (A) 0.2 7.

g) References..............................................................................................5 OBJECTIVE This experiment was carried out to study the conduction of heat along a composite bar and evaluate the overall heat transfer coefficient. INTRODUCTION Conduction is defined as the transfer of energy from more energetic particles to adjacent less energetic particles as a result of interactions between the particles. In solids‚ conduction is the combined result of molecular

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

PHYS 124 – 3:30 Th Lab 5: Joule Heat John Doe 4/3/2014 Introduction The objective of this lab is to learn that whenever there is an electrical current in a conductor‚ there is some electrical energy that is converted into heat energy. The heat generated in an electrical circuit is commonly referred to as joule heat. Sir James Joule studies of these separate phenomena lead him to the discovery of the proportionality constant known as the Joule equivalent of heat‚ denoted by J. The Joule equivalent
