SUPERPOSITION Question 1: (Multiple Wells) As shown in the figure below one recharging and 2 discharging wells are operated simultaneously. All the wells have the same diameter 30 cm. The discharge of the recharging well is 85 lt/s and the discharges of the discharge wells are identical and is 70 lt/s. The original piezometric (or water table) level within the aquifer is 50 m. Storage and transmissivity values are 0.0002 and 0.0015 m²/s respectively. If the wells are operating simultaneously (i.e. the flow condition is unsteady) what is the drawdown at the discharging well A at time t-30 hrs, if the aquifer is: 40 m 24 m a- Confined [i.e. s= Q 4nT B Q=75 lt/s W(u)] Q=75 lt/s 18 m b- Unconfined [ i.e. s-- Q=85 lt/s s² 2h, 4nT W(u)]

When there are only a few upstream calming distances available, the annular venturi meter is helpful for metering flows in pipe systems. The cylindrical component of the annular venturi meter is installed inside a pipe, as seen in the image. Between the upstream pipe and the area close to the cylindrical portion, the pressure differential is monitored. In the system, air flows under normal circumstances. 10 cm is the pipe's diameter. The interior pipe diameter to the diameter of the cylindrical portion is 0.8. Water pressure is measured to be off by 5 cm. Track down the system's volume flow rate. Assume the flow is constant, incompressible, and viscous, and that the velocity is distributed equally throughout the pipe sections. Utilize typical air conditions at 25 °C and 101 kPa.

Water flows through pipe A whose diameter is 30 cm and into parallel pipes 1, 2 and 3 and out through Pipe B (diameter= 30 cm). The properties of the pipe are as follows: for pipe 1, L= 300 m, diameter = 10 cm f= 0.020; for pipe 2 L= 240 m diameter= 15 cm f= 0.018 and for pipe 3, L= 600 deiameter= 20 cm f= 0.017. The upstram junction has an Elev. 90 m with pressure of 205 kPa; the downstream junction is at Elev. 30 m. If the average velocity in pipe A is 3.0 m/s, find the flow rate in pipe 3. include your free body diagram. a.24.68 L/s b.80.21 L/s c.107.11 L/s d.212.0 L/s
