7.1 Energy, Work, and PowerThe energy equation involves energy, work, and power as well as machines that interact with flowing fluids.These topics are introduced in this section.When matter has energy, the matter can be used to do work. A fluid can have several forms of energy. Forexample...
energy equationviscous workThe Bernoulli equation is arguably the most commonly used equation in fluid mechanics. For the incompressible, inviscid flow along a streamline, the Bernoulli equation states that the total head of the fluid (the sum of the pressure head, velocity head, and elevation ...
may have to be taken into account in some circumstances, but are not usually included in general fluid mechanics relationships. Enthalpy and entropy need to be considered for gas flow analysis (see Section 1.5.8). The basic energy-flow equation is the steady-flow energy equation: (1.29)Q˙+...
The Bernoulli equation is arguably the most commonly used equation in fluid mechanics. For the incompressible, inviscid flow along a streamline, the Bernoulli equation states that the total head of the fluid (the sum of the pressure head, velocity head, and elevation head) is constant. Neglecting...
Pumps and Fans - Energy Equation and Head Rise The energy equation can be used to calculate the head rise in pumps and fans. ADVERTISEMENT Actual Head Rise of a Pump or Fan Using the Energy Equation the head rise through a pump or fan can be expressed as: ha = (p2 - p1) / γ +...

3.5A. Steady Flow Energy Equation (SFEE)(a) Recap:Closed system:no mass flow across the boundary (control mass considered)NFEE Q + W = ∆U Open system:mass flow across the boundary (control volume considered)Will the kinetic energy of the fluid affect the energy balance? What other ...
The Mechanical Energy Equation in Terms of Energy per Unit Volume The mechanical energy equation for a pump or fan (1) can also be written in terms of energy per unit volume by multiplying (1) with the fluid density - ρ : pin + ρ vin 2/ 2 + γ hin + ρ Eshaft = pout + ρ...
6) hydrostatic equation 流体静力学方程 例句>> 补充资料:流体力学的能量方程 是在密度均匀情况下反映机械能守恒的方程;在考虑密度、温度、内能变化时,反映包含内能的能量守恒定律(见热力学第一定律)的方程。根据所考虑的因素多少,流体力学的能量方程具有不同的形式。对于流场中一切量都是光滑函数的情况,它可列成...
Equation (9) is derived from the equation of mass conservation 𝜌˙+∇·(𝜌𝐮)=0ρ˙+∇·(ρu)=0, where 𝜌ρ is the density and 𝐮u is the velocity of the fluid, with 𝜌˙ρ˙ being the partial derivative with respect to time. Now, assume that the azimuthal velocity ...
