“For a well draining 80 acres, with thickness 80 ft and permeability 15 md, assume Bo = 1.2, μ = 1.8 cp, rw = 0.3 ft, and the flow is steady-state flow following the Vogel correction. Plot IPRs in one figure for skin va“ues of s = 0, 5, 10, and 20. Assume the reservoir and bubble-point pressure are 5000 psi.”
A hydraulic jump takes place in a rectangular channel downstream of a spillway. The flow in the channel is Q =900 cfs. The conjugate depth (y1) upstream of the jump was measured at 1.4 feet. The channel width is B = 15feet. (a) Compute the conjugate depth y2 downstream of the hydraulic jump.(b) What type of jump are we looking at in this problem? Refer to the five types presented (in the figureabove) by Prof. Ven Te Chow, the father of watershed hydraulics and physical hydrology.(c) Evaluate the specific energies E1 and E2 at points 1 and 2 (upstream and downstream of the jump,respectively) and the specific energy Ec corresponding to the critical depth yc. Then annotate thespecific energy diagram below with the values of y1, y2, yc, E1, E2, and Ec.(d) How much is the head loss in the hydraulic jump? Explain your answer.
A hydraulic jump occurred in a rectangular channel of 5 m bottom width and flow rate of Q=21.5 m3/sec. If the water- depth before the jump was, Y=0.4 m , determine the water- depth after the jump. Notes: The answer should be in 2 decimal points. - No need to write the unit.
