This is a subjective question, hence you have to write your answer in the Text-Field given below. In figure below, when a sudden contraction is introduced in a chemical safety horizontal pipe line from 50 cm to 25 cm, the pressure changes from 10,500kg/m2(103005N/m2) to 6900kg/m2(67689N/m2). Calculate the rate of flow of the chemical. Assume co-efficient of contraction of jet to be 0.65 Following this if there is a sudden enlargement also noticed in a chemical safety horizontal pipe line from 25cm to 50cm and if the pressure at the 25cm section is 6900kg/m2(67689N/m2) what is the pressure at the 50cm enlarge section?
