The steel beam ABCD is simply supported at A (pin) and supported at B and D by steel cables each having a diameter of 12mm. A force of 20 kN is applied at point C. For steel, let E = 209 GPa. Determine the stresses in the cables and the deflections of points B, C, and D if (a) beam ABCD is considered rigid and (b) beam ABCD has I = 8(10^5) mm^4. Points A, B, C, and D are all on the beam and are 500mm apart. The lengths of cables B and D is 1m.
What is the velocity head expressed in atmospheres for a rapid filter operated at a surface loading rate of 475 m/d when the local porosity is 0.40?
Determine the maximum temperature in the tank. Take the thermal conductivity of the wastes as 2.0 W/mK.
150,000 mol of aqueous phosphoric acid (H3PO4) solution contains 5.00% H3PO4 by moles. The solution is concentrated by adding pure H3PO4 at a rate of 20.0 L/min.
If the pH of a natural water is 7.8, and the alkalinity was measured to be 125 meq/L, determine the following: - Alkalinity as mg/L CaCo3 - Approximate the total carbonate concentration (Ct), in moles per liter.
The influent suspended solids concentration to a primary settling tank is 435mg/L. The average flow rate is 0.050m3/s. If the suspended solids removal efficiency is 60 percent, how many kilograms of suspended solids are removed
Wastewater from a paper mill contains ultimate BOD of 200ppm and DO of 3ppm, water is discharged at a rate of 100,000 gallons per day into a river, the river has a flow of 1 million gallons per day with no BOD
In 2003 at Holloman Air Force Base in New Mexico, test engineers set a world record by moving 192 lb payload at 6,453 miles per hour in a rocket sled. The rocket sled track, built in 1954, is 15.44 km in length.
A separator accepts waste oil at 70% oil and 30% water by weight. The top product stream is pure oil while the bottom underflow contains 10% oil. If a flow of 20 gal/min is fed to the tank, how much oil is recovered
Find the discharge flowing over a rectangular sharp crested wire, in GPM, which has a width of 9.9 feet and a discharge coefficient of 3.24, if the head above the crest is 1.74 feet.
A concrete sewer pipe is running under the finished water tank. The pipe can resist up to 2000 psi of applied pressure.Would the pipe be able to resist the applied pressure due to the water tank
The salt water mixes thoroughly with the fresh water and the mixture overflows out of the tank. If the flow rate out of the tank is 60 liters/minute. Assume freshwater is 1000 kg/m^3, and the salty water is 1020 kg/m^3.
An electron is released from rest at a perpendicular distance of 9.9 cm from a line of charge on a very long nonconducting rod. That charge is uniformly distributed, with 9.0 ?C per meter. What is the magnitude of the electron's initial accelerati..
