5.2.1: Exponential Growth and Decay Models (Exercises)

WebContinuity Equation Flow Rate The first rate of change of interest for fluid in motion is the mass flow rate: the amount of mass that passes through a checkpoint in one unit time. Or, mathematically, \text {mass flow rate} = \frac {\Delta m} {\Delta t}. mass flow rate = ΔtΔm. WebAn exponential growth or decay function is a function that grows or shrinks at a constant percent growth rate. The equation can be written in the form f (x) = a(1+r)x f ( x) = a ( 1 + r) x or f (x) = abx f ( x) = a b x where b = 1+r. b = 1 + r. Where: a a is the initial or starting value of the function. r r is the percent growth or decay rate ... nash dome oil field
