    I would say it is Boyle's law P1V1=P2V2, ik you would be thinking, they only gave us length, but since cross-section is the same, so volume ratio should be also same a length, here is the solution V1=45 v2=45-15=30 p1=100kpa p2=? =(45*100 000)/30=150 000=150 kpa EZ;) *just noticed my post is...
