WebbThe actual intake air volume can be calculated function of air mass ma [kg] and air density ρa [kg/m3]: Va = ma / ρa (4) Replacing (4) in (3) gives the volumetric efficiency equal to: ηv = ma / (ρa · Vd) (5) Usually, on the engine dynamometer, intake air mass flow rate is measured [kg/s] instead of air mass [kg].

Pump displacement per revolution and driven speed are multiplied to determine the theoretical flow. For example, if the pump has a displacement of 200 cc/rev and is turning at 500 RPM, the flow rate is 100L/min. {\eta }_v=\frac{Actual\ flow\ rate\ by\ the\ pump}{Theoretical\ flow\ rate}\times 100\% or inb mbs means

WebbAnalysis of the flow line in Figure 1 shows that the water flow has diffluent rates in the horizontal and vertical directions and belongs to the plane two-dimensional flow. If the Dupuit assumption can be introduced and the vertical diffluent rate is neglected, the calculation can be simplified to a one-dimensional flow calculation in the x direction [ 32 ]. inb meaning
