Mechanical energy balance equation
WebThe initial balance is written for the total energy and then the part involving the kineti c energy (known as the mechanical energy balance, obtained by taking a dot product of Cauchy’s equation with the velocity) is subtracted. After using some thermodynamic relationships, the final form of the equation of conservation of thermal energy is ...

Webh = u + p v, we apply the differential operator to give. d h = d u + p d v + v d p. Now, we know that the d u term can be expanded using fundamental thermodynamics. Namely, the change in the internal energy of the system ( d u) is equal to the heat transfer to the system minus the work done by the system. In equation form, this means that. WebTypically it is often easiest to just choose the lower of the two points (1 or 2) as the height where h=0 h = 0. The P P refers to the pressure at that point. You can choose to use gauge pressure or absolute pressure, but …

Our general mechanical energy equation, letting v = v a v g and α = 1, is ( P ρ + 1 2 v 2 + g z) 2 − ( P ρ + 1 2 v 2 + g z) 1 = w s − w f Considering our specific system, this general equation reduces to P 2 = P 1 − ρ w f Because w s > 0 and P 2 < P 1, it is clear that the frictional work has lead to a pressure loss/drop in our pipe.
