Suyu daha düşük bir seviyedeki bir rezervuardan daha üst seviyedeki bir rezervuara kaldırmak için saniyede 7500 jullük bir basınç uygulayan bir santrifüj pompanın akış hızının hesaplanması gerekiyorsa, enerji denklemi kullanılabilir.
Rezervuarlar arasındaki seviye farkı 10 metre, yük kaybı ise 5 metredir.
Her iki rezervuarın yüzeyleri atmosfere açık olduğundan, hem giriş hem de çıkıştaki basınç ve hız sıfırdır, bu da enerji denklemini daha da basitleştirir.
Burada pompanın basma yüksekliği, net şaft güç girişinin bölümü ile suyun birim ağırlığı ve debinin çarpımı ile elde edilir.
Basitleştirilmiş enerji denklemi yerine pompanın kafası kullanılırsa, pompanın akış hızı elde edilebilir.
Ayrıca, akış hızı için ifadede verilen değerlerin değiştirilmesi, suyun pompalanma hızını gösteren nihai değeri verir.

enerji denkleminin uygulanması

Enerji denkleminin santrifüj pompalara uygulanması, akışkanlar dinamiği ve mühendisliğinde temel bir ilkedir. Bu senaryoda, enerji denklemi, farklı yüksekliklerdeki iki rezervuar arasında su transferinden sorumlu bir santrifüj pompanın debisini hesaplamak için kullanılır. Pompa saniyede 7500 joule enerji girişi uygular ve alt ve üst rezervuarlar arasındaki dikey fark 10 metredir. Ek olarak, sürtünme ve diğer dirençlerden kaynaklanan basınç kaybı 5 metredir. Bu parametreler, debiyi enerji denklemini kullanarak çözmek için önemlidir.

 Her iki rezervuar da atmosfere açık olduğundan, pompanın hem girişindeki hem de çıkışındaki basınç, atmosfer basıncına eşittir. Bu, enerji denklemindeki basınç terimlerinin birbirini götürmesini sağlar. Ayrıca, giriş ve çıkıştaki hızlar ihmal edilebilir olduğundan, denklemdeki hız terimleri de ortadan kalkar. Bu özel durum için enerji denklemi yalnızca yerçekimi ivmesi ve pompa yüküne bağlıdır.

 Pompanın ürettiği yük, net şaft güç girişinin debisi ve suyun özgül ağırlığının çarpımına bölünmesiyle belirlenir. Bu yükü enerji denklemine koyup pompanın debisi çözerek belirlenebilir.

Application of the Energy Equation

centrifugal pump flow rate calculation

Centrifugal pump flow rate can be calculated with the energy equation. In this problem, water moves between two reservoirs at different elevations, and the pump provides the energy needed for the transfer. The pump input is 7500 joules per second, the elevation difference is 10 meters, and the head loss from friction and other resistances is 5 meters.

Both reservoirs are open to the atmosphere, so the pressure at the inlet and outlet is the same. That means the pressure terms in the energy equation cancel. The flow at the inlet and outlet is also negligible, so the velocity terms drop out as well.

With pressure and velocity terms removed, the equation depends on the gravitational head and the pump head. The pump head is found by dividing the net shaft power input by the product of the flow rate and the specific weight of water. Substituting that head into the energy equation makes it possible to solve for the pump flow rate.

Continuity Equation for a Fixed Control Volume

The continuity equation describes conservation of mass for a fixed control volume. In fluid mechanics, a system is a collection of the same contents over time, and its mass stays constant. That idea is the starting point for deriving the equation. To analyze flow, a fixed, non-deforming control volume is chosen so it matches the system at one instant. The Reynolds transport theorem then links the system to the control volume. It shows that the rate of change of system mass has two parts: mass...

Continuity and Velocity in Pipe Flow

Conservation of mass explains how fluid moves through a fixed control volume such as a pipe or duct. In a fixed, nondeforming control volume, the total mass stays constant unless mass enters or leaves through the control surfaces. For steady, incompressible flow, the mass entering the system equals the mass leaving it. A sewer pipe is a useful example of this idea. It can be treated as a fixed control volume with inlet and outlet control surfaces around the flow region. Because the fluid is...

Stormwater Detention Basin Mass Balance

Stormwater detention basins use mass balance to manage runoff during heavy rainfall. These basins are especially important in urban areas, where impervious surfaces can increase flooding risk. Engineers use the conservation of mass to track how water enters, is stored in, and leaves the basin. In a detention basin, the control volume is the water inside the basin. Its boundaries are the basin walls, the inflow pipes, and the outflow structures. During a rain event, water comes in through the...

linear momentum in control volume

Momentum Balance for Fluid Control Volumes

Linear momentum balance for a fluid control volume links Newton’s second law to moving fluid. The law says that the rate of change of linear momentum equals the sum of the external forces acting on the system. In a fluid system, this idea helps explain how motion and force are related. A control volume can match the fluid system at a specific moment. When that happens, the forces on the control volume and the system are the same. Reynolds transport theorem explains this connection by splitting...

Forces in a 180° Pipe Bend

Forces in a 180-degree pipe bend can be found by applying the linear momentum equation to flowing water. The pipe has a constant cross-sectional area of 0.01 square meters, and the water moves at 15 meters per second. The pressure at the inlet is 0.2 megapascals, and the pressure at the outlet is 0.16 megapascals. The goal is to find the force components in the x and y directions that hold the bend in place. In this case, the flow is only in the y direction at both the entrance and the exit.

Wind Turbine Torque and Angular Momentum

The moment-of-momentum equation helps explain how wind turbine blades create torque. Torque is the turning effect of a force around an axis. In rotating systems, this equation links the motion of the wind with the force acting on it. The equation begins with Newton's second law for a fluid particle. That law says the rate of change of linear momentum equals the external force on the particle. To find torque, the position of the particle relative to the rotation axis is combined with that force.

conservation of energy in control volume

Turbine Work from Energy Changes

A turbine can turn fluid energy into shaft work when flow passes through a control volume. The fluid enters the turbine at one point and leaves at another. Under steady-flow conditions, there is no energy buildup inside the control volume, so the stored energy does not change with time. This steady-flow setup makes the energy equation simpler. The turbine is treated as doing mechanical work, and heat transfer is taken as negligible, so Q̇ is approximately zero. The flow at the inlet and outlet...

design example: forces in sluice gate

Sluice Gate Water Pressure and Reaction Force

Sluice gates control water flow in channels, reservoirs, and irrigation systems. They work as vertical barriers with an opening that can be raised or lowered. Changing the opening height changes the water velocity and pressure below the gate. The forces on a sluice gate depend on the water depths upstream and downstream, written as z1 and z2. When the gate is closed, the upstream water depth is greater. That creates a strong pressure difference across the gate and a net force toward the...
