The exit age distribution of a fluid leaving a vessel (denoted by E) is used to study the extent of non-ideal flow in the vessel. The value of ∫∞ 0 E.dt is____________________?
Correct answer: B. 1
- A. 0
- B. 1
- C. ∞
- D. √2π
Explanation
E(t) is a normalized probability density for the exit ages of fluid elements. Consequently, the total area under the E-curve, ∫₀∞ E(t)dt, must equal 1.
