The length of a football field from goal post to goal post scales 49.15 mm on a vertical photograph. Find the approximate dimensions (in meters) of a large rectangular building that also appears on this photo and whose sides measure 20.5 mm by 6.8 mm. (Hint: football goal posts are 120 yards apart.)
Calculate carbonate, noncarbonate, and total hardness Na+ = 27.8 mg/L Cl- = 35.6 mg/L Ca+2 = 48mg/L CO3-2 = 30 mg/L Mg+2 = 12mg/L HCO3- = 61 mg/L K+ = 12 mg/L SO4-2 = 48 mg/L
A 4-m-long rigid beam is supported by a pinned connection and cable. the beam weighs 2.0 kn and hangs horizontally when unloaded When the beam is not loaded the solid cable is 4.00 m long and has a solid area of 175 mm1
In an irrigation system sometimes water must be pumped over long distances. Consider a system that consistes of a 1 m diameter, 2 km long commercial steel pipe, which connects a river to an irrigation canal.
You are expected to present the estimated increase in stresses and settlement of the existing office complex will due to the construction of your office building. Prepare your analysis and presentation.
compare the efficacy of oxide-induced crack closure for aluminum alloys with that for steels solely on the basis of the volume of oxide produced on the fatigue fracture surface.
The Metrodome's inflatable roof covers 10.0 acres and its interior volume is 60.0x103 cubic feet. During construction, 40.0x103cubic yards of concrete, 11.9x103 tons of reinforcing steel, and 5.00x102 tons of structural steel were utilized.
A company produces two kinds of septic tanks: type A and type B. Each type B tank takes twice as long to produce as a type A tank. If it only produced type A tanks, the company has the time to produce a maximum of 2000 tanks per week. The supply of m..
A rectangular channel 5 m wide carries a discharge of 10 m^3/s at a uniform depth of 3 m. The channel is running on a slope of 0.0025 m/m. Estimate wall shear stress and friction velocity. Assume the density of flowing water as 1000 kg/m^3.
calculate departures and latitudes, misclosures in departures and latitude, and traverse relative precision. Balance the departures and latitude using the compass rule, and calculate coordinates of points B, C, and D.
A 50,000 L/day stream of wastewater must be heated from 15 degrees celsius to 40 degrees celsius for a treatment process to work properly. at what rate must we put heat into the stream? assume that wastewater has thermal properties exactly like pure ..
Calculate the additional stress as a function of depth that a temporary construction wall , like that shown in Figure As 1, must take as the result of a crane sustained in the zone above it.
A small nitrogen container is at Pressure P1 = 5 bar and T1 = 300 K. It's been filled from a larger nitrogen container, which is P= 10 bar and T = 300 K. The filling process ends when pressure in the small container
