You are designing a 31-story apartment building in a large city. Assume that it will be fully sprinklered. What types of construction are you permitted to use under the International Building Code? What re resistance rating will be required for the separation between the apartment oors and the retail stores on the ground oor , assuming the different occupancy areas must be separated? What classes of nish materials can you use in the exit stairway? In the corridors to those stairways ? Within the individual apartments ? If a Red oak board has a ame-spread rating of 100, can you panel an apartment in Red oak? What Þ re resistance ratings are required for partitions between apartments? Between an exit corridor and an apartment ? What type of Þ re door is required between the apartment and the exit corridor? What is the required re resistance rating for the walls around the elevator shafts? For the purposes of this exercise, when referring to Figure 22.7, assume the highest rating requirement where a range of requirements is provided.
You plan to use a tank of total volume V= 10 m3 to remove a contaminant at concentration Cin = 1 g/m3 from a waste stream with a flow rate of Q = 1 m3/h. The reaction is first order with a rate constant k1 = 0.5 h-1.
Drawdown at an observation well 15 m from the pumped well is 3.0 m, and drawdown at a second observation well 150 m away is 0.30 m. find the hydraulic conductivity of the aquifer.
a) What was the discharge capacity andvelocity at full flow at the time of installation b) If the pipe presently carries a flow of15 cfs when full, determine the present velocity and present value of n.
Find the point load strength index in the two directions and compute the point load strength anisotropy index 1,(s0)
A soil profile consists of 3 m of clean sand (?= 19 kN/m3) over 6 m of marine clay (?= 16 kN/m3, kv = 10-9 m/s) over 3 m of silty clay (?= 17 kN/m3, kv = 2 X10-9 m/s).
Determine the torque that the Titanium Alloy shaft can transmit if the allowable angle of twist is 0.375 RAD. Assume the torque is applied at the end of the shaft. The shaft is 2 meters long and has a diameter of 25 mm.
A solution of HOCl is prepared in water by adding 15 mg HOCl to a volumetric flask, and adding water to the 1.0 L mark. The final pH is measured to be 7.0. What are the concentrations of HOCl and OCl
An Engineer is considering the development of a small wind turbine (D=1.25m) for home applications. The design wind speed is 15 mph at T=10C and p=0.9 bar. The efficiency of the turbine is n=20% meaning that 20% of the kinetic energy in the wind can ..
Why would an orange farmer worry about his crops on a cloudless, dead-claim night with lows predicted to be 35 F but sleep easy if it's overcast and windy? Explain your answer form the perspective of transport phenomena to receive full credit. (Th..
A piston-cylinder device contains 0.85 kg R-134a at 263K. The piston is free to move and has a mass of 12 kg and diameter of 25 cm. The atmospheric pressure is 98 kPa. Heat is added to the cylinder until the R-134 temperature = 10 o C.
what are biosynthetic pathways in cells A) anabolic B) catabolic C) usually produce more atp than they consume D) release monmorsinto the cytoplasm
The position of a car traveling between two stop signs along a straight city block is given by r=[9t-(43/2)sin(2t/5)]m, where t denotes time and 0s
