questions refer to Activity 2: Studying the Effect of Viscosity on Fluid Flow. 5. At what viscosity level was the fluid flow rate the highest? 1.0 6. Describe the relationship between flow rate and viscosity. The relationship is inversed; meaning a fluid that has a high viscosity has a slow flow because it resists the flow. Fluid that has a low viscosity will flow faster because it is less resistance to the flow. 7. Was the effect of viscosity greater or less than the effect of radius on fluid

Abstract The researchers are trying to figure out the effects of sedimentation‚ activated carbon‚ and decantation and boiling on purifying used coconut‚ palm and vegetable oil. The researcher’s experiment resulted to the change of appearance‚ odour and viscosity of each type of oil. The now purified cooking oil is faster to heat which makes cooking easier‚ faster and more efficient. The purified oil is quite beneficial however it does not take in as much taste as the unpurified ones. Overall the experiment

diethyl ether and methanol‚ with the filtrate collected via vacuum filtration. Potassium hydroxide pellets were added to the filtrate‚ the ether was distilled off‚ and the mixture was saponified by reflux. The crude cholesterol was isolated through a series of ether extractions and aqueous washes; then the ether was dried with MgSO4 and removed by rotary evaporation. The melting point of the yellow‚ sticky crude product was 91-119 oC. This crude product was then recrystallized from methanol‚ yielding 0

Distillation is a process in which compounds that are in the same solution become separated by their boiling points. For this to occur‚ a heterogeneous mixture has to be placed into a distiller‚ in this experiment a solution of 1:1 water and methanol was distilled. When distilling substances there are various methods of distillation that can be used. In this lab‚ simple and fractional distillation was used. The simple distiller is composed of a 100ml round bottom flask that is attached to: a

homeostasis within the body. The previously completed experiments each had the objective of understanding how various factors may have an influence on blood flow rate. These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as the effect of blood vessel length‚ and the effect of blood pressure. This better understanding of cardiovascular dynamics was achieved with PhysioEx 9.1. Hypothesis: Hypothesis- Activity 1: Studying the Effect of Blood Vessel Radius
