Forced Convection Heat Transfer I. Introduction This laboratory deals with forced convection, forced convection can be considered as a staple of heat transfer. That is to say that forced convection can be found in almost any heat transfer problem, and thus understanding its importance and how it affects a given problem is one of the more important learning objectives/outcomes of heat transfer. When dealing with forced convection the most important section, after understanding how convection

effective time require to sufficiently cook a given body mass of turkey by increasing the relative humidity (RH) inside a conventional oven while keeping the inside temperature at 100°C. Prior to cooking, the turkey initially at – 17 °C is first raise to a temperature of 29 degrees by immersion in water about room temperature. This immersion cause weight gain because of water absorption and since the process is a sensible heat transfer phenomenon the temperature of the carcass can best be monitored

In heat transfer, there are three modes for the transfer of heat named as Conduction, Convection and Radiation. Every mode has its unique importance in a specific area. Convection heat transfer reflects an advantage as it utilizes the heat transfer by means of a fluid either static or in motion. Convection by means of a stagnant fluid implies “Natural convection” whereas by means of a fluid in a motion reflects a “Forced convection”. In a Natural convection flow, buoyancy and density effects are

and some assumptions were made to aid the mass and energy balance. After the mass and energy balance was completed and the flow rates and salt content for all streams obtained, the heat duty required by each heat exchanger was also estimated from the values obtained in the mass and energy balance and also using the specific heats required. The heat transfer area of the heat exchangers were calculated as well based on the heat duty, heat transfer coefficient of each heat exchanger and the log mean

kinetic energy has now begun to transfer into elastic potential energy. How much the ball deforms depends on the elasticity of the ball which refers to how easily an object can revert from and back to its original shape. (Reference.com, 2016). The greater the elasticity of a ball, the greater bounce height it will reach due to its greater flexibility, causing it return to its original shape. This is because a greater elasticity results in a more efficient transfer of energy, since less energy is

Abstract Hot tubs are very popular across America due to their relaxation as well as health benefits. Hot tubs have been attributed health benefits ranging from relief of muscle and joint pain, to help in treatment of HIV and other viral infections. Because of this, many people own hot tubs and many more go to health spas where they can use them. On the other hand, hot tubs are not that easy to maintain. A consistent disinfectant level must be maintained in order to inhibit the growth of

sorbent are greatly dependent on their particle size and distribution throughout the mass. Effective size and uniformity coefficient are the two important parameters for treatment of contaminated water using adsorbent as filtering media in column operation where control of particle size is critical. The effective size corresponds to the sieve size through which 10% of the material will pass, and the uniformity coefficient is the ratio of the sieve size that will just pass 60% of the material to the effective

surrounding. The methods by which heat can be transferred are conduction, convection and radiation. Conduction is the transfer of energy from one object to another by contact and it will depends on factors such as surface area of the objects and thermal conductivity, k, is the property that indicates how good conductor of thermal energy is certain material (2). Convection is the transfer of energy due to a bulk motion of a fluid and can only be experimenter by liquids or gases (2). Finally, radiation

collector mainly depends upon the characteristics of working fluid. Conventional solar flat plate collector uses water as heat transfer fluid but it gives lower thermal efficiency. Nanofluids have superior thermal and optical properties that can be used to increase heat transfer rate. So our aim is to design and develop solar flat plate collector using Nanofluid as heat transfer fluid.   1. Introduction 1.1.
