Turpentine is stored in a 25-ft-diameter tank. Inside the storage tank, the turpentine depth is 18 ft. A piping system containing a pump is to move the turpentine to a holding tank having a very large diameter. The turpentine depth in the holding tank is constant at6 ft. The pipeline contains a basket strainer three elbows, and a ball valve. At the exit, the end of the pipeline is submerged 5 ft below the free surface of the turpentine. For...

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...

A centrifugal pump is used to pump water at 77ºF from a reservoir whose surface is 20 ft above the centerline of the pump inlet. The Pipe System consists of 67.5 ft of PVC pipe with a 1.2 in ID and negligible average internal roughness height. The length of the pipe from the bottom of the lower tank to the pump inlet is 12 ft. There are several minor losses in the pipe: an acute edge entry (KL = 0.5),...
