We wish to study the flow due to a line source of strength m placed at position (x, y) = (0, +L), above the plane horizontal wall y = 0
We have studied the point source (sink) and the line source (sink) of infinite depth into the paper. Does it make any sense to define a finite-length line sink
Water flows upward in a pipe slanted at 30°, as in Fig. The mercury manometer reads h = 12 cm. What is the pressure difference between points (1) and (2)
Water flows through the duct in Fig which is 50 cm wide and 1 m deep into the paper. Gate BC completely closes the duct when ß = 90°
Water flows downward in a pipe at 45°, as shown in Fig. The mercury manometer reads a 6-in height.
Water flows steadily through the round pipe in the figure. The entrance velocity is Vo. The exit velocity approximates turbulent flow, u = umax(1 - r/R) 1/7.
Water flows through a circular nozzle, exits into the air as a jet, and strikes a plate. The force required to hold the plate steady is 70 N
Water flowing through an 8-cm-diameter pipe enters a porous section, as in Fig. which allows a uniform radial velocity vw through the wall surfaces
Water enters the bottom of the cone in the figure at a uniformly increasing average velocity V = Kt.
Water, flowing in a channel at 30-cm depth, undergoes a hydraulic jump of dissipation 71%. Estimate
Wet air, at 100% relative humidity, is at 40°C and 1 atm. Using Dalton's law of partial pressures, compute the density of this wet air and compare with dry air

Water at 20°C flows through the piping junction in the figure, entering section 1 at 20 gal/min, the average velocity at section 2 is 2.5 m/s.
Water at 20°C is to be siphoned through a tube 1 m long and 2 mm in diameter, as in Fig. Is there any height H for which the flow might not be laminar
Water at 20°C flows through a 5-cm-diameter pipe which has a 180° vertical bend, as in Fig .The total length of pipe between flanges 1 and 2 is 75 cm.
Water at 20°C flows steadily through the box in Fig entering station (1) at 2 m/s. Calculate the
Water at 20°C flows steadily at 40 kg/s through the nozzle in Fig If D1 = 18 cm and D2 = 5 cm, compute the average velocity, in m/s
Water at 20°C flows steadily through a reducing pipe bend as in Fig Known conditions are p1 = 350 kPa, D1 = 25 cm, V1 = 2.2 m/s, p2 = 120 kPa
Water at 20°C flows past a half body as shown in Fig. Measured pressures at points A and B are 160 kPa and 90 kPa, respectively, with uncertainties of 3 kPa
Vortex shedding can be used to design a vortex flow meter. A blunt rod stretched across the pipe sheds vortices whose frequency is read by the sensor
