Chemistry Lab Report Purpose The purpose of this lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette

Change Modeling in FLUENT FLUENT can be used to solve uid ow problems involving phase change taking place at one temperature e.g.‚ in pure metals or over a range of temperature e.g.‚ in binary alloys . Instead of explicitly tracking the liquid-solid front as the phase change occurs‚ which requires a moving mesh methodology‚ an enthalpy-porosity formulation is used where the ow and enthalpy equations are solved with extra source terms on the xed grid. Marangoni shear‚ due to the variation of

Project 5 Lab Assignment Lab 10.1 Using your results How did you score? (Include score) How high are your daily and weekly stress scores? The highest score daily is around 10 pm when I have to drive from one campus to the other to get to class in time and I have to deal with all the people driving. And my highest score weekly is usually Saturday and Sunday that are the days that I work the whole day. Are you satisfied with your stress rating? If not‚ set a specific goal. I am actually

Impacts of solid waste on health The group at risk from the unscientific disposal of solid waste include – the population in areas where there is no proper waste disposal method‚ especially the pre-school children; waste workers; and workers in facilities producing toxic and infectious material. Other high-risk group include population living close to a waste dump and those‚ whose water supply has become contaminated either due to waste dumping or leakage from landfill sites. Uncollected solid waste

Combustible Liquids (Examples: alcohols‚ esters‚ ethers‚ ketones) Vapors from flammable and combustible liquids can mix with air and burn if they contact an ignition source. Possible ignition sources include hot electrical wires‚ hot surfaces‚ open flames‚ hot particles and embers‚ and sparks. The lowest temperature at which a liquid releases enough vapor to start burning is called the flash point. The flash point is what distinguishes a flammable liquid from a combustible liquid. Flammables:
