題組內容
一.敘述或定義下列統計名詞或定理：（每一小題5分）
(1)中央極限定理(The Central Limit Theoiem)
其他申論題
【已刪除】2. The mass conservation equation lias Ihe form . Do we need to assume the flow is “steady” in order to derive the incompressible flow continuity equation? Please discuss and derive it. (20%)
#210934
3. Please explain the definition and physical meaning of flow streamline in details. Why these streamlines can be treated as “solid boundaries”？ Can we simply just assume the “noslip” boundary condition on these streamlines? Explain why. (20%)
#210935
【已刪除】4. At low Reynolds number, the volume flow rate Q through a small tube is only a function of (he tube radius R, Ihe fluid viscosity p., and the pressure drop per unit tube length dP/dx. Now derive this function Q=f(RJ fj. ,dP/dx) through the dimensional analysis. (Hint; isNavier-Stokes equation) (20%)
#210936
【已刪除】5. Air flow steadily belween Iwo sections in a long, straight portion of 4-inch inner diameter pipe as shown in the diagram. The uniformly distributed temperature and pressure at each section are given, [f the average air velocity (non-uniform distribution) at section (2) is l000ft/s, please calculate the average air velocity at section (1). (20%)
