HEAT TRANSFER SYMBOLS AND FORMULAS CLASS NOTES Heat transfer symbols and formula are very helpful understanding the topic in great depth with lot of ease. These make the learning simple and convenient. Symbols also reduce the learning time. Fig. Conduction through a Composite Wall (linear Temperature Variation) Fig. Conduction through a Cylinder (Logarithmic Temperature […]
DIMENSIONLESS NUMBERS CLASS NOTES FOR ENGINEERS Convention equations in terms of non-dimensionless numbers reduce the number of variables. This makes the equations convenient and easy to handle. It reduces the time and level of difficulty. Dimensionless numbers do not have any units. Use Reynolds number to know laminar, turbulent or transition flow. In every dimensionless […]
HEAT TRANSFER INTRODUCTION CLASS NOTES FOR MECHANICAL ENGINEERING Compare heat transfer with the transfer of a Government employee. Heat transfer is heat in motion. The driving force for heat transfer is temperature difference. Heat flows from a body at higher temperature to a body at lower temperature. It is an irreversible process. Greater is the […]
