The Figure below (Figure 3) shows a pipe system with a valve and two reservoirs
QUESTION3 The Figure below (Figure 3) shows a pipe system with a valve and two reservoirs. A pump transports a constant flow rate of Q = 0.1 m3/s of water from reservoir A to reservoir B. At four sections the pipe has bends and the roughness of the pipe is ks = 1.5 mm. The pipe has a diameter D = 34 cm and a total length L = 500 m. The water level in reservoir B is Δh=4.67 m above...

The system below shows a simplified schematic of an oil transfer system between tanks, from left to right: L L The oil specific gravity is 0.77 and its viscosity is 2.7 [cP). The pipes are horizontal and coaxial (neglect difference in height between suction and discharge). The tanks are closed but vented so that they are at atmospheric pressure ([atm]). Assume for simplicity that the liquid level in each tank is 2.5 (m) above the level of the pipes (in...
