The Evolution of the Chem-E-Car Design 1st E-Car Design The first E-Car design attempt is based on an exothermic reaction of an acid (HCl) and Baking Soda (NaHCO3). NaHCO3 will be placed in a vessel that has a valve at the bottom. When the valve is open, the reaction will be initiated and CO2 will be liberated. The chemical reaction is: NaHCO3 + HCl à NaCl + 2H2O + CO2 The CO2 liberated will create a pressure gradient. …showed first 75 words of 251 total…

The reason that we made changes to the first design is due to the slow reaction to produce carbon dioxide, and also the pressure losses in the tubes will be very huge since the gas line is relatively long. By moving the position of the turbine, we will minimize the pressure drop. ------------------------------------------------------------------------ **Bibliography**
