WebbUsing the equation for the mass flow rate to determine the velocity at point 2: m ˙ 2 = ρ A 2 v 2. v 2 = m ˙ 2 ρ A 2. v 2 = 8000 lbm hr ( 62.4 lbm ft 3) ( 0.2006 ft 2) v 2 = 639 ft hr ( 1 hr 3600 sec) v 2 = 0.178 ft sec. Now we can use the Extended Bernoulli equation to determine the required pump head. 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].
