Air at 100 kPa and density of 1.2 kg/m3 flows upward through a 5-cm diameter inclined duct at a rate of 50 L/s. The duct diameter is then reduced to 4 cm through a reducer. The pressure change across the reducer is measured by a water manometer. The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 0.1 m. Determine the differential height between the fluid levels of the two...

2. (10 points) A uniform air flow in a duct of 10 cm diameter is connected a manometer using working fluid of specific gravity of 0.7. The square well of the slant-tube manometer is sufficiently large that the elevation of the manometer fluid in it does not change T-200 significantly when fluid moves up in the leg of the manometer. When there is no flow in the duct, the liquid surface in the manometer les at 2.3 cm measured on...

Liquid saline flows steadily along the duct in Figure 1, which is part of an infusion set. The duct has constant cross-sectional area Ao-18 mm. The fluid velocity at the inlet section is Vo 0.35 m/s. A drug is added to the saline through a side port connected to the main duct at an angle θ 45°. The cross-sectional area of the side access is A1-10 mm2 and the drug is injected with velocity V,-0.8 m/s. The drug has the...

Question 2 (30 marks) (a) A fluid flowing into a nozzle with specific enthalpy of 2980 kJ/kg and the velocity is 80 m/s. At the exit of the nozzle, the specific enthalpy of the fluid drops to 2670 kJ/kg. The nozzle orientation is horizontal and the heat loss is negligible. Given that the nozzle inlet area is 0.25 m2 and the specific volume of the fluid is 0.2 m2/kg, calculate the velocity of the fluid at exit, the mass flow...

Water (density = 1000 kg/m3) flows through a duct that makes a 180 degree U-shaped bend (see below). Assume that the fluid is incompressible through the duct and the velocity at the inlet is V1 = 24 m/s. Assume that the momentum-flux correction factor at both inlet (point 1) and outlet (point 2) is 2.1. The gage pressures are P1 = 120 kPa at the inlet and P2 = 248 kPa at the outlet of the bend. The inlet is...
