Question 1 a) Explain using the concept of depth changes and specific energy why Bernoulli's equation cannot be used to derive the Hydraulic Jump formula. (10) b) Derive the Hydraulic Jurnp formula starting with the conservation of momentum that states Net Pressure Force is equal to Change in Mornentum using discharge per unit width i.e. /,9Y1 = P9(it — V2) where location 1 is upstream of the jurnp and location 2 is downstream.

A pin-ended chord of a truss is treated as a member in a braced frame. Its length is 12 ft. It must carry a tension dead load of 95 kips and live load of 180 kips along with a uniformly distributed transverse dead load of 1.2 kips/ft and live load of 2.3 kips/ft. Will a W8x67, A992 member be adequate if the transverse load is applied to put the bending about the strong axis? Determine by (a) LRFD and (b) ASD. [8.14- 12-Tension]

How the Green Certification of buildings could aid in creating projects that are environmentally responsible and resource efficient?

1. Using the flow rate of 250 gpm, select a plastic pipe diameter (2”, 4”, 6”, 8”, 10”…) & determine the approximate pump head based on the following:
   1. Minor pipe losses include 6-90 degree bends (standard) and one plug valve straightway. Document your source for your K-values.
   2. Document which calculation method you used to calculate the total pump head.
   3. To save energy, choose the largest pipe diameter that provides the recommended 2.0 fps velocity of flow.
   4. Assume nominal pipe diameters as the inside pipe diameter.
   5. The connection is 10,500 feet from the pump station.
   6. The connection point located at an elevation of 768.6 feet above MSL. The low water elevation in the station (at which point the pump will turn off) is 755.0 feet above MSL.

Recommended Pipe Diameter = __________________ inch

Total Pump Head = _______________________ ft

what is creep ? Discuss the theories propounded to explain probable causes of creep.

Vehicles arrive at a signalized intersection at a uniform rate of 900 veh/hr. The saturation flow rate for the intersection is 1200 veh/hr. However, a crash has reduced the saturation flow rate to only 300 veh/hr for a one-hour period. Assuming D/D/1 queuing, determine:

a. How long will it take for the resulting queue to clear? (6 points)

b. How much delay is experienced as compared to if the saturation flow rate had NOT been reduced? (6 points)

c. What is the average delay per vehicle during the period over which queuing occurs? (4 points)

d. What is the average queue length during the period over which queuing occurs? (4 points)

"How could a solid understanding of Project Management Plans contribute to the potential employability of an engineer? (Why is it important to know about this?). In your response, propose methods for how this engineer could demonstrate their knowledge to a potential employer (Beyond showing them a copy of a Project Management Plan)."

A field density test has been run on a soil containing 18% of its weight in particles retained on the No. 4 sieve. The dry density of the total sample was 128.7 pcf and the water content was 7%. The water content of the gravel fraction was 3%. the specific gravity of the solids was 2.69. Compute the water content and dry density of the soil fraction of the fill that passes the No. 4 sieve.
