Water is flowing from a higher to a lower reservoir through a 24-inch pipe that has a Darcy friction factor of 0.02. The local loss coefficients for the bends, entrances, and exits sum to 3.5. The pipe connecting the two reservoirs is 5000 feet long, and the reservoirs differ in elevation by 100 feet. What is the flow rate in cfs from the higher to the lower pipe? A pump which runs at 80% efficiency, is available to pump water back from the lower to the higher reservoir at a velocity of 1.0 f/s. What power (in Horsepower) must be supplied to this pump?
Compute and compare the hydraulic conductivity (m/s) of a formation with respect to the three liquids below. The formation has a permeability k = 0.1 darcy and g = 9.8 m/s2. Liquid viscosity (g/cm s) density (g/cm3)
A stream conveying a flood peak of 50 m3/s (velocity 1.25 m/s and depth 1 m) is divided into 1 km long reaches for solution of the unsteady equations. Determine the largest value of ft for which the solution will be stable.
The frame is desinged to carry the hanging mass at G equal to 167 kg. The frame is supported by a pin connection at C and the rope AB, and constructed with pin connections at points E, F, and D.
