Water flows steadily downwards through a circular pipe of internal diameter 0.15 m inclined at 30° to the horizontal. A U-tube manometer is used to determine the pressure difference between two points displaced axially along the pipe by a distance 1.25 m. The reading on the manometer is 0.25 m of mercury. 1.25 m 0.15 m 30 0.25 m mercury Figure 2: Manometer and pipe Neglecting the thickness of the wall, determine between points 1 and 2: a.

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...
