Pump Input Power = P Formula – 1 Here Q = Flow rate in m3/sec H = Total developed head in meters ρ= Density in kg/m3 g = Gravitational constant = 9.81 m/sec2 η = Efficiency of the pump ( between 0% to 100%) Formula – 2 ...
EquationThe standard equation used to solve for water horsepower (WHP) is:WHP = Q x H / 3960where:WHP is the water horsepower Q is the discharge or flow rate in gallons per minute (GPM) H is the total head in feet 3960 is a constant that results from the conversion factors between ...

The energy wasted in the pump is the difference between the required BHP and the hydraulic power. This is the energy converted to heat, Q, in the pump; if expressed in British thermal units per minute, we obtain the following formula: (3.5)Q=42.41Phydr(1ηp−1) where Q = wasted en...
Also, there is a simple equation for the frequency of relaxation oscillations, containing the parameter r. However, such equations then often do not hold for (quasi-)three-level gain media.More to Learn Encyclopedia articles: threshold pump power lasers relaxation oscillations four-level and three...
Formula (16) is the basic equation for the lifting design method, where l represents the chord length of the airfoil, and 𝑙/𝑡l/t represents the cascade density, which reflects the effective cascade channel area. The basic equation of the lifting design method expresses the relationship bet...
where Pin stands for the charge power (or shaft power). Pout is the positive power shifted via this selected centrifugal pump to the fluid. It was specified as shown in the equation below: 𝑃𝑜𝑢𝑡=𝜌×𝑔×𝐻×𝑄Pout=ρ×g×H×Q (8) Currently, it is a generally accepte...
Ideally, this compound serves to raise your metabolism, which forms one part of the weight-loss equation. Increases Strength Another reason to use RAD140 is that it gives you more strength. This is attributed to its steroidal properties that activate rapid metabolism in the body. With increased...
The use of existing large pumping station equipment for upstream residual water reverse power generation is an unrealized yet valuable renewable energy project. At present, some large axial flow pump stations have begun to perform reverse power generatio
