1. The T-beam shown below is made of regular weight concrete (specific weight 150 lb/ft3 (pcf)). Determine the dead load per foot length of the beam in pounds per foot (plf). Neglect the weight of the steel reinforcement.
2. An 8-ft high building wall consists of 12-in. clay-brick and 2x4 unplastered wood studs on both sides. Determine the load the wall exerts on the floor in pounds per foot (plf) length of wall.
3. The second floor of a light manufacturing building is constructed from a 5-in. thick stone concrete slab with a 4-in. cinder fill topping (see the figure below). If the suspended ceiling of the first floor consists of metal lath and gypsum plaster, determine the dead load for design in pounds per square foot of floor area.
4. Determine the reactions on the beam. The support at B can be assumed a roller; support at A is a pin.
5. Determine the vertical reactions at the supports A and B. Assume the support at A acts as a roller and the connection at B is a pin.
6. Determine the reactions on the beam. The beam has pin support at A and roller support at B. Note that the support at B is bearing against a sloping surface as indicated in the figure.
Phenol undergoes a first-order decay reaction in the CSTR with rate constant, k = 0.50 hr^-1. The current industrial pre-treatment permit for Phenol is 20 mg/l. The permit limitation may be changed, either higher or lower, in the future.
A slurry containing 20 percent by weight of limestone (CaCO 3 ) is processes to separate pure dry limestone from water. If feed rate is 2000kg/h, how much CaCO 3 is produced per hour?
In part (a) of this question we are asked to calculate τmax. In order to do this we separate the cross section at the neutral axis and take the entire upper half (as shown in the cramster solution).
calculate the cracking moment (resisting moment) for an unreinforcedconcrete beam that is 10 in. wide, 16 in. high. assume normal weight concrete with 3000 psi = f prime sub c. use the internal couple method and check with the flexure formula.
An activated sludge process receives 4000m^3 / day containing 120 mg BOD /L from the primary settling tank and 3500 m^3/day Containing 25mg BOD/L from the secondary settling tank.
How to design a simply supported rectangular concrete beam havingcross section of 20 mm by 40 mm and a length of 3 meters that couldcarry a uniform load of 1000 KN.
The aluminum bar has an electrical coil imbedded in it, so that known amounts of heat can be transferred to it. Aluminum has a specific gravity of 2.70 and a specific internal energy given by the formulaU (kJ/kg)=0.94T(C).
a 4ft-long, 1-in-diameter shaft rotates inside an equally long cylinder that is 1.02 in. in diameter. Calculate the torque required to rotate the inner shaft at 2000 rpm if SAE-30 oil at 70 degrees F fills the gap
Calculate the pH of a buffer solution prepared by mixing 8.5g KH2PO4 with 43.5g K2HPO4 in 1 liter of water (this is actually the composition of the dilution water used in a BOD test. Follow the same procedures you have been using for previous acid/..
Assume the only products are CO2, H2O, CO and N2. State results as the CO molar fraction of both wet and dry exhaust products ( wet exhaust products include H2) and dry exhaust products exclude it).
Water flows past a triangular flat plate oriented parallel to the free stream. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar boundary layer flow.
Calculate the density in g/cm^3 of Ba and its atomic radius.
