12-100 Exam 3 28 April 2008 Use three significant figures in your calculations. Gravitational acceleration = 32.2 ft/s 2 ; One gallon = 0.13368 ft 3 1. The water supply for a city flows in an open channel 8 ft wide, as shown. The water depth is observed to be 3.5 ft when the channel delivers 120 MGD (million gallons/day). Calculate the associated velocity in ft/s. (25 pts) 2. A cylindrical water tank has a diameter of 10.0 feet and initially holds 16,000 gallons.

Unformatted text preview: It drains through a pipe of 2 in diameter at its bottom, for which a loss coefficient K of 2.35 has been measured. The valve is opened and is then closed after 9,000 gallons have been removed. • Determine the velocity, in ft/s, and the volumetric flow rate, in gal/min, just after the valve is opened. (25 pts) • Determine the time required to drain 9,000 gallons. (50 pts)...
