Engineering Mechanics - Dynamics Chapter 15 Since v er is constant, integrating, with t = 0 when m = m 0 yields v er ln m m 0 a 0 g + () t = m m 0 e a 0 g + v er t = The time rate fuel consumption is determined from Eq.[1] t m d d m a 0 g + v er = t m d d m 0 a 0 g + v er e a 0 g + v er t = Note : v er must be considered a negative quantity. Problem 15-130 The jet airplane of mass M has constant speed v j when it is flying along a horizontal straight line. Air enters the intake scoops S at rate r 1 . If the engine burns fuel at the rate r 2 and the gas (air and fuel) is exhausted relative to the plane with speed
