Question

b) s d the height of water of the first tank was increased to 45minstead of so my, the pre per unit of length (Pa/m will: Remains constant Increase Decrease Cannot be determined 7. a b) The flow through this pipes is considered as: Steady, Uniform. Incompressible Unsteady. Non-Uniform. Incompressible Steady. Uniform, Compressible Unsteady, Uniform, Compressible d) 8. Minor losses through valves, fittings, bends, contractions etc. are commonly modelled as proportional to a Static Head b) Velocity Head s Pressure Head d) All of the above Use the following figure to answer questions 9-11 Free je 10.02m (3) 10 Air 0.04 m HII Water The figure shows a Venturi channel of circular cross section. Before Air stars to flow were equal. Compressibility and viscous effects are negligible. Assume pair=1.21 kg/m . And g=9.85 m/s2. Determine
