Find the depth and top width of a triangular notch capable of

discharging a maximum quantity of 700 lit/sec and such that the

head shall be 8 cm when the discharge is 6 lit/sec. The K for the

notch is the same as for a right angled notch, that has a value

of, K = 1.42.

A simply supported flanged beam subjected to a factored load of 60 kN/m (including dead load and live load). The beam has an overall depth of 600 mm including slab thickness of 100 mm. The width of the beam is 230 mm, effective span of the beam is 6.25 m and effective cover to the tension reinforcement is 50 mm. Assume M25 grade concrete and Fe415 steel. Check whether the beam needs to be designed as singly reinforced or doubly reinforced

Construction Safety

1. Corporate safety plans, site specific safety plans, and emergency response plans are very long and detailed. Employees are usually trained in the application of these plans but what happens to workers and the company if an employee with duties in these plans does not remember something they are responsible to do in the plans when an accident or emergency happens? Please write a comprehensive answer including 1) possible reasons what went wrong, 2) what can be the consequences and 3) how it should be avoided in future (one page)

1.1 The average effective overburden pressure on a 10 mts – thick layer in the field is 136 kN/m2 and the average void ratio is 0.98. If a uniform surcharge of 200 kN/m2 is applied on the ground surface, determine the consolidation settlement for the following cases, Cc = 0.35, Cs = 0.08.
a)Preconsolidation pressure, σ'p = 350 kN / m2 b) b)Preconsolidation pressure, σ'p = 150 kN / m2

1.2 For case b) of the previous exercise determine, a) What is the void ratio at the end of 100% of consolidation. b) If Cv = 1.5 mm2 / min, how long will it take to settle the first 100 mm? Take the two-way drain for the clay layer.

Calculate Liming Requirements. You have a soil sample with a CEC of 10 meq / 100 g soil, a pH of 4.8 and a BS of 37%. You would like to raise this soil to a pH of 6.5, so you need to raise the BS to 65%. You also have a Mg deficiency. Assume 93% purity of your liming agent. During screening of a 100g sample, you had 1.5 g on the 8-mesh screen, and 13.4 g on the 60-mesh screen. Choose the appropriate liming agent and calculate CCE, ECCE, and the tons of lime you need to apply to your 100 acre field.

Construction of a new fright terminal along a rural highway has been proposed. During certain periods of the day, significant numbers of large trucks are expected to depart the terminal’s one-lane driveway to access an interstate highway. Developers would like to know if there are an adequate number of time gaps (headways) in the highway traffic to permit about 40 trucks per hour to enter the highway without the need for a traffic signal. To permit a truck to safely enter the highway, a time gap of at least 8 seconds is needed. Assuming that there will be a flow of 850 vehicles on the highway during a design hour, how many gaps or opportunities will there be during the design hour for trucks to enter the highway without a traffic signal? Assume that vehicle arrivals follow a Poisson distribution.
