# 13.7.1.4: Total Pressure Loss


The total pressure between two points, ($$a$$ and $$b$$) can be calculated with integration as

$\Delta P_{ab} = \int_a^b \dfrac{dP}{dx} dx \label{phase:eq:TdeltaP}$

and therefore

$\Delta P_{ab} = \overbrace ParseError: invalid DekiScript (click for details) Callstack: at (Bookshelves/Civil_Engineering/Book:_Fluid_Mechanics_(Bar-Meir)/13:_Multi–Phase_Flow/13.7:_Homogeneous_Models/13.7.1:_Pressure_Loss_Components/13.7.1.4:_Total_Pressure_Loss), /content/body/p[3]/span[1], line 1, column 1  ^{friction} + \overbrace ParseError: invalid DekiScript (click for details) Callstack: at (Bookshelves/Civil_Engineering/Book:_Fluid_Mechanics_(Bar-Meir)/13:_Multi–Phase_Flow/13.7:_Homogeneous_Models/13.7.1:_Pressure_Loss_Components/13.7.1.4:_Total_Pressure_Loss), /content/body/p[3]/span[2], line 1, column 1  ^{acceleration} + \overbrace ParseError: invalid DekiScript (click for details) Callstack: at (Bookshelves/Civil_Engineering/Book:_Fluid_Mechanics_(Bar-Meir)/13:_Multi–Phase_Flow/13.7:_Homogeneous_Models/13.7.1:_Pressure_Loss_Components/13.7.1.4:_Total_Pressure_Loss), /content/body/p[3]/span[3], line 1, column 1  ^{gravity} \label{phase:eq:TdeltaPpart}$
