Using A36 steel select the lightest equal leg single angle member to resist a factored (LRFD) tensile load Pu = 167 kips. The member will be connected through one leg with one line of three 3/4-in Ø bolts spaced at 3 in between centers as shown. The edge distances Leh = Lev = 1.5 in.  Use LRFD Method Use U from Table D3.1, Case 8. See attached (D3.1 Case 8, Shear Strength of Bolts, Table 1-7 Dimensions of Angles).

The system in Fig. consists of 1200 m of 5 cm cast-iron pipe e=0.26mm, two 45° and four 90° elbows, a globe valve, and a sharp exit into a reservoir. If the elevation at point 1 is 400 m, what gage pressure is required at point 1 to deliver 0.005 m3/s of water into the reservoir? U= 10-6m² 1 * sec -, K 45° elbows= 0.2, K 90° flanged = 0.2, K globe valve 10, K Sharp exit=1 G Elevation 500 m 45° Open globe 45° Sharp exit

: The 6-cm-diameter pipe in Fig. contains glycerin [specific gravity 0.95], flowing at a rate of 6 m³/h. Verify that the flow is laminar. For the pressure measurements shown, is the flow up or down? What is the indicated head loss for these pressures? 3.7 atm B 2.1 atm 12 m A

The following assumptions may be used in the design: a. Each of the four apartment buildings is occupied by 50 residents. Each apartment building is four stories high. Each story is 3 m high. b. Each house is occupied by three residents. c. Average daily demand for the village is 500 Lpcd. d. Peaking factor is 6.2 for peak hour demand. e. Needed fire flow…

Two group of students are collecting traffic data at the two sections A and B 200 meters apartalong a highway. Group A shows that 5 vehicles pass those sections at interval of 8, 9, 10, 11and 13 sections respectively. If the speeds of the vehicles were 80, 72, 64, 56 and 48 kmph.Compute : (i) the time mean speed (ii) space mean speed, and (b)what will be the averagedensity of the above traffic stream

A person entering public transport center to purchase intercity Bus ticket. There is two ticket line to purchase tickets. Each ticket purchase takes an average of 12 seconds. The average arrival rate is 3 persons/minute. Find (a) Probability of having one traveler in the system, (b) the average length of queue, (c)average waiting time in queue, (d) average time spend in system. Arrival follows Poisson distribution and service time follows negative exponential distribution.
