Consider the compression of 75 kg/s of carbon dioxide from 1 bar and 45 °c to 50 bar. 3.2.1 calculate the work requirements and outlet temperature for a 1-stage, 2-stage, 3-stage and 4- stage compression system. assume polytropic compression and an efficiency of 85%. assume that the inter-stage coolers reduce the temperature to 45 °c (12) 3.2.2 comment on the work requirements and the discharge temperatures for the various systems

the answer is alpha particles hope i you

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
