Chapter 6, Problem 6.3.1P

Q1. An oil flows through 50.0 m of cast iron pipe having a diameter of 0.25 m. If the volumetric flow is 0.40 m^3/s, determine the head loss in the pipe. Take Kinematic Viscosity as 0.120* (10^-2) m2/s.

Question 2 Figure Q2 shows a flownet for a concrete dam with a sheet pile cut-off at the upstream face. The soil beneath the dam has a permeability of 2×10-7 m/sec. 6m AVA 18m Dam Impervious Figure Q2 9m 7m 2m 12m AVAVAVAVAWAY (a) Explain what these solid and dashed lines in Figure Q2 represent and their physical significance in engineering application. (b) Using the flownet above, estimate the flow rate beneath the dam and the uplift water pressure at Points A and B on the bottom of the concrete dam. (c) Using the flownet above, estimate the vertical effective stress at Point C. The saturated unit weights of soil and unit weight of water are taken as 20 kN/m³ and 10 kN/m³, respectively.

HURREVAC is the model run by NHC to estimate storm surge potential. True False

In a 12cm diameter pipe, the major losses are equal to 5.0v²/2g. Find The equivalent length of pipe to account for the major losses for f = 0.04.

Can anyone explain what is that kind of diagram and why it has 2.5 sg? Need asap
