The purpose of this manual is to serve as instructional book for students‚ technical staff and instructors to assist in performing and understanding the experiments in Transport Phenomena. In the second edition‚ two new experiments on kinematic viscosity and vapor pressure determinations have been included in Fluid Mechanics and Mass Transfer sections respectively. The old experiments have been revised to eliminate errors and induce

Feeding of Hollow Cylindrical Castings P.K.Sandell Chief Executive‚ Sandell Associates‚ Kolkata‚ India and Vienna‚ Virginia‚ U.S.A OP-37 internal centerline shrinkage‚ which was unacceptable. A major factor is the blockage of feed metal flow which result in micro-porosity or voids in the solid casting. These voids add up to produce a centerline shrinkage. FEEDING Feeding covers methods adopted to produce castings without shrinkage defects. In the case of solid solution alloys like steel

The Paranormal and Mass Hysteria The paranormal has always been hotly debated. Often mass hysteria is blamed as a factor in people’s belief in the paranormal. Mass hysteria contributes to the events surrounding paranormal activity by amplifying people’s emotions‚ such as fear and nervousness. Mass hysteria is defined as an assumed threat that causes physical symptoms among a large group of people (Yelnick). The whole sociological concept of mass hysteria preys on anxiety‚ fear‚ and the community

Scientific Paper on Diffusion 2 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using two tests: the glass tube test and the agar-water gel test. In the glass tube set-up‚ two cotton plugs soaked in two different substances (HCl and NH4OH) were inserted into the two ends of the glass tube. The substance with the lighter molecular weight value (NH4OH‚ M = 35.0459 g/mole) diffused at a faster rate (dAve = 25.8cm)‚ resulting in the formation of a white ring around the

Abstract The cytoplasm and extracellular environment of the cell are aqueous solutions. They are primarily composed of water (the solvent)‚ and a variety of dissolved solutes‚ such as sugars‚ amino acids‚ and ions. The plasma membrane of the cell is selectively permeable‚ allowing water to freely pass through‚ but regulating the movement of solutes. Water and some dissolved solutes move via passive diffusion through the plasma membrane. Diffusion is a process where molecules move from an area of
