Petrol pump is very commonly used space...we rarely stop to see what it is all about, This time we stopped at our neighborhood petrol pump during outdoor visit to understand working of petrol pump. We discovered that we have right to ask for ‘purity check’ and each petrol pump display that.
After knowing how billing is done, rates and transport of petrol, we explored properties of petrol. What is temperature and density has to do with the purity or quality of the petrol, we are still pondering.
Filter paper test gave us glimpse about purity and our rights to have pure petrol. This is just beginning to know what happens at petrol pump, how it happens and how things works :).
