Hp filter equation
Web19 okt. 2006 · Since the two filters are in cascade, the frequency response of the combination is the product of individual frequency responses. eg: H (w) = 1/ (1+jwR1C1) * 1/ (1+jwR2C2) If you know the values of R1,R2,C1,C2 the plug those into this equation and simplify it to get something that looks like H (w) = 1/ (1+jwRC) WebUsing 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.
