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 ...
If working in metric units, you need to convert to the appropriate units (cubic meters per second for flow rate and meters for head) and adjust the constant in the formula accordingly. Is it possible for WHP to be zero?Yes, if there is no flow (Q=0) or no head (H=0), WHP ...
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...
The Formula for PSI: Feet of Head/2.31 = PSI Flow is the volume of water a pump can move at a given pressure. Flow is indicated on the horizontal axis in units like gallons per minute, or gallons per hour, as shown in Figure 2.Fig. 2. A basic pump performance curve for ...

from bottom dead center to top dead center is denoted by V0, if the flow path resistance of the outlet flow path is denoted by R, and if flow velocity in the outlet flow path when the actuator produces one cycle of output energy is denoted by Q(T), the following formula is satisfied...
One thing to note is that the power steering fluid has oil present in it while the transmission fluid doesn’t have any oil element in its formula. So, it’s very much possible for there to be leakages if these fluids are used in one system with rubber parts because oil can cause the...
(In Formula (7), K1is a value based on the deviation between the target fuel pressure and the actual fuel pressure) A predetermined initial value is stored as the high power integral learning value before learning execution of the integral term TIME_F/B_I. ...
The coherence of the flow rate referring to the formula (= volumetric flow rate) Q of the pump is: Q = ηVol ⋅ Vg ⋅ n The volumetric efficiency ηVol shows the relationship between the actual and the theoretical flow rate. The existing differences result from internal movement of the...
