Total pressure drop & static pressure drop
hello everyone.. i have a doubt about total and static pressure drops.here is my questions.
1.consider a pipe which having small bend, for that if i measured total pressure drop will give idea about how energy get loss by fluid flow. so we can think about modification on bend or something. but measuring static pressure drop at inlet and outlet is for what purpose? 2. if flow is get recirculated at the bend,then what about the overall total & static pressure drop of the pipe? they will increase or decrease? |

So For a pipe or bend which have same inlet and outlet diameters, static and total pressure drops should return same value. I would recommend always go by total pressure drop to compare the energy lost in due to pipe friction or bend or anything else. |
Any time that dissipative effects take a role, the total pressure diminuishes as it indicates the total kinetic energy that can be obtained. Dissipation degrades the potential level of kinetic energy as internal energy takes more relevance.
