4.12.4 Calculation of the Working Dimensions of the Formed Parts For the calculation of the working size of the molded parts‚ there are the average shrinkage method and the limit size method. The average shrinkage method is used to calculate the working dimensions of the stress cone cavity. According to literature [55]‚(3-14): the cavity size of the formula: (1) The radial size of core and reentrant mold 1) Size calculation L_M=[(1+S_max ) L_s-∆_1 ]_0^(+δ_z1 ) =[(1+2.2%)×42-0.36]_0^(+0.12) = 42

The percent change in mass between the total mass of 10 un-popped kernels and total mass of 10 popped kernels was approximately 18.83 %‚ which is also the same for the percent change of mass between the 1 un-popped kernel and 1 popped kernel. The reason why there’s a percent change in mass is due to the experiment being done in an open system‚ which is a systematic error. The open system is a systematic error because during the period of time to measure the mass of the popped kernels‚ the escaped

During an experiment‚ there was a glass eye dropper placed into a bottle filled to the brim with water with the cap closed. The glass eye dropper floated in the bottle when the bottle was left alone. When the bottle was squeezed‚ however‚ the glass dropper sunk to the bottom. When the pressure was released from the bottle‚ the dropper floated back to the top of the bottle. The dropper floated at the top of the bottle when no pressure was applied‚ because the air inside the dropper was less dense

PHY 114: Absorption of Nuclear Radiation Abstract: The purpose of this experiment was to determine the mass thickness attenuation factor for beta rays when they pass through polyethylene sheets of varying thicknesses. This was done by using an apparatus that measured the seven different intensities and then taking these values‚ putting them through a number of calculations and finally generating a graph of ln(I_corr) versus the thickness of the polyethylene sheets. Once this graph

Senior Science Half-Yearly Revision 1. Surface tension - A property of the surface of a liquid. It is what causes the surface portion of liquid to be attracted to another surface‚ such as that of another portion of liquid. Surface tension is caused by cohesion (the attraction of molecules to like molecules). Since the molecules on the surface of the liquid are not surrounded by like molecules on all sides‚ they are more attracted to their neighbours on the surface. Mercury has a high surface

Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can
