Determine the emissivity (Ɛ) of an element experimentally. 2. Determine the Heat transfer coefficients by free convection Theory Natural Convection: Heat transfer through circulation of fluid due solely to gravity Forced Convection: Heat transfer through circulation of fluid due to forced fluid movement (fan‚ pump‚ etc.) Radiation: Heat transferred by surface photon emission‚ typically only significant at T>>Room Temp.

the separate materials. This objective of this experiment is significant in that it gives valuable information on how to determine the material composition of an object when given very vague information. From information learned in the accompanying Fluid Mechanics lecture course‚ basic formulas can be applied to solve for the specific weight of the object in question. The experiment performed will involve the buoyancy principle and include calculating the volume displaced of a submerged object. This

Even though has been described as “water on the brain” it is a clear fluid surrounding the spinal cord and brain called (CSF) cerebrospinal fluid. The excessive accumulation of cerebrospinal fluid is an result in an abnormal widening of spaces in the brain called ventricles. The fluid has an effect that helps prevent the vital brain tissue from injury. The fluid is made continuously

Cavitation and may lead to complete failure of the pump. Fluid Type and Specification : The Nature of fluid is very important to know before selecting a pump. Impeller Design‚ Metallurgy of the pumps and type of pumps are largely dependent on the specification of the fluid. Few Considerations to be taken care are Solids to be handled‚ Temperature of fluid‚ Corrosive and abrasive nature of fluid ‚ toxicity of fluid and we should check if the fluid is highly flammable .

achieve similitude; 1. Geometric similarity – The model is the same shape as the application (they are usually scaled). 2. Kinematic similarity – Fluid flow of both the model and real application must undergo similar time rates of change motions. (Fluid streamlines are similar). 3. Dynamic similarity – Ratios of all forces acting on corresponding fluid particles and boundary surfaces in the two systems are constant. BEFORE THAT!! The application is analyzed in order to satisfy the conditions; 1

The main focus of this experiment is the heating and cooling of the oil fluid. This was achieved using the heating component in the heat exchanger and water flowing from the tap. Varying temperatures and flow rates were used via adjusting the heating component and the control valve respectively to determine the effect each had

MICROENCAPSULATION Microencapsulation: Definition: It is the process by which individual particles or droplets of solid or liquid material (the core) are surrounded or coated with a continuous film of polymeric material (the shell) to produce capsules in the micrometer to millimetre range‚ known as microcapsules. Microencapsulation (Cont.): Morphology of Microcapsules: The morphology of microcapsules depends mainly on the core material and the deposition process of the shell. 1- Mononuclear
