Objective: Study of heat transfer in Shell and Tube heat exchanger. Introduction: Heat Exchanger is device that facilitates heat exchange between two or more fluids. They are used wherever efficient heat energy transfer is required particularly petrochemical plants‚ petroleum refinery‚ natural gas processing‚ air conditioners and refrigerators‚ sewage treatment etc. Considering wide spectrum it swaps ‚ the device is a necessity in most of the industrial applications.

experiments while the other consists of a disc for radial profile studies. Both test section are equipped with an array of temperature gradient. The instrumentation provided permits accurate measurements of temperature and electrical power supplied to the heater. Fast response temperature probes‚ with a resolution of 0.1°C‚ give direct digital readout in °C. The power control circuit provides a continuously variable electrical output of 0-80 Watts nominal (at nominal supply voltage) with direct digital readout

as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes

Optimization of Room Air Conditioning with Desiccant Wheel 1. Introduction Desiccant air conditioning technology is an emerging alternative air conditioning technology having many advantages over conventional VAC system. Desiccant cooling technology is free from CFCs‚ can be operated with low grade energy (heat energy) and capable of precise control of latent heat load of conditioned space. This eco friendly and energy saving method of air conditioning has drawn interest of many researchers over

The total cost for the supplies are $430.00 (copper piping‚ one 30 gallon electric water heater‚ and PVC piping). The rate for the plumbers with no overtime and no weekend work is $65.00 per hour at straight pay. Based on the number of hours allowed for the installation of the plumbing‚ the total cost for plumbing labor amounts to $18‚720.

“Energy and Efficiency analysis of 210MWe coal base Thermal Power Plant with running parameters” Goutam Khankari‚DVC‚Kolkata. INTRODUCTION Power projects are essentially capital intensive. Not only they involve a highly initial cost which is around Rs. 4.5 to 5.0 crores per MW for coal-based plants but also huge operation cost. The running expenses of a 210MW thermal power station may range around thirty crores every month and usually about 80% of this goes towards the fuel cost. Not only fuel

Energy Efficient Building Windows Energy efficient windows have multiple layers of glass. The reason for this is because the more layers of glass you have the better it insulates the house. Three or four layers of glass are one of the best because you have more airspace in between layers. A smaller airspace doesn’t insulate the building as well as a thicker airspace would. The thickest an airspace should be is 1 inch because any thicker than that will cause the glass of the window

Accounting Alternatives Case At the beginning of the year 20x1‚ two companies began operations to sell home heating units. Eads Heaters Inc. is located in Eads‚ Colorado‚ and Glenwood Heating Inc. is in Glenwood Springs‚ Colorado. The companies operate under similar economic conditions and have identical operations during the year. However‚ each manager makes different accounting choices and estimates when applying generally accepted accounting principles (GAAP) in preparing the company’s financial
