2. Design a storage and distribution system for the town of Waffle. The requirements are that fire protection shall be provided, the minimum water pressure at the top of the apartments is to be 240 kPa and the maximum system pressure is to be 550 kPa. The following assumptions may be used: Each of the four apartment buildings is occupied by 50 residents. Each apartment building is four stories high. Each story is 3 meters high. Each house is occupied by three residents. Average daily demand for the village is 500 Lpcd and the peak hourly demand factor is 6.2. Needed fire flow for the houses is 230 m3/h. and for apartment building is 500 m3/h, with 2 h duration. System pressure is to be provided from the elevated storage tank. Minor pressure losses in buildings may be ignored. The distribution system will not contain any loops. Assume that emergency supply (ES), fire department supply (FDS) or off peak pumping are not provided (they are all equal to zero). Provide the following…

1. The city of Ten Sleep proposes to use Crater Lake for its water supply. Water quality analysis results revealed no detectable Giardia, viruses, or Cryptosporidium in the source water (Giardia cysts <1/100 L; Viruses <1/100 L; Cryptosporidium oocysts <0.075/L). Design a disinfection system to treat 3,500 m³/d by direct filtration and chlorine dioxide (CIO2) will be used as a primary disinfectant. The filtered water has a pH of 7.5 and a temperature of 5°C. Provide the following information for your design: • Determine the total removal/inactivation required for disinfection for each pathogen group • Determine the required CT value to achieve the required inactivation for the design conditions (pH, temperature)

A simple supported one-way slab spans 24 ft. In addition to its own weight, it supports an uniformly distributed service live load of 100 psf. A masonry wall, which has a service dead load of 1500 lb/ft, is also supported by the slab along with an uniform service floor live load (a line load) of 500 lb/ft loaded as shown below in the figure. (a) (b) Select the depth of the slab using ACI Code's minimum thickness requirements where deflections are not computed. Design the primary steel and temperature steel and show your results in a sketch. The concrete is light-weight concrete and has a unit weight of 110 lb/ft³. Assume 3/4 inch cover on the reinforcement aand that f' 3 ksi and f₁ = 60 ksi. Use #6 bars for the primary steel and #4 bars for the shrinkage and temperature steel. Assume interior exposure, and use ACI 318-19. Repeat part (a) NOT using the ACI Code's minimum thickness requirements for cases where deflections are not computed. Use #6 bars for the primary steel and #4 bars…

Water (at 10° C has n = 1.31 x 106 m²/s) flows from reservoir A (surface elevation 100 m) through a 2.25-m-diameter concrete pipe (e = 0.36 mm; f=0.014) to reservoir B (surface elevation 91.84 m). If the 2 reservoirs are 17 km apart, find the flow velocity V (to 2 decimal places x.xx) ignoring minor losses. 100 m A L = 17 km P₁ h₁ + = + V² 2g D=2.25 m 91.84 m B + h₂ 2g P₂ = =h₂+ + V

The floor system of an apartment building consists of a 4-inch-thick reinforced concrete slab resting on three steel floor beams, which are in turn supported by two steel girders, as shown below. The areas of cross section of the floor beams and the girders are 18.3 in.2 and 32.7 in.², respectively. Determine the dead load acting on the beam CD.
