If you have to fit three number 10 bars and 2 number 8 bars in a rectangular beam of 12 inch width you may need to use two rows. Given;
beam is 24 inch deep, the steel stirrup used is number 4,a 1 1/2 inch.
concrete cover on both sides. Sketch how you will place the bars and calculate the location of the effective depth. Place as many bars in the lower layers as possible.
A car weighing 4000 pounds strikes the stopping barrier depicted below head on at a speed of 70 mph. The stopping force in the barrier is a function of how far the car penetrates into the barrier.
The flowrate Q over a rectangular sharp crested weir depends on the width of the notch b, the head on the weir H, and the acceleration due to gravity g. Find how many dimensionless parameters govern this problem.
A homogeneous coarse sand deposit has a water table at 10 m depth. The water coefficient of permeability of the sand is found to vary significantly with height above the water table even though the sand deposit is homogeneous.
A certain fluid at 15 psia is contained in a cylinder behind a frictionless piston. The initial volume of the fluid is 300 in^3. The fluid expands to a volume of 450 in^3 while the pressure increases to 25 psia.
1.For an SO2 emission rate of 22,000 kg/day and an exhaust gas flow rate of 5.0 million m^3/hour(after the scrubber) measured at 150 C and 1atm pressure, calculate the concentration of SO2 in the exhaust gases(ppm).
What is the major head loss in a coarse concrete pipe with a diamter of 1ft that is 100 ft long. Water flows at a rate of 20 ft^3/s (viscosity of water = 2.344x10^-5 lbfs/ft^2, density of water = 1.94 slugs/ft^3) 1inch = 25.4mm
Torque is transferred through two shafts by means of gears. If the diameters of gears B and C are in the ratio 1:2, what should the ratio of shaft diameters be so that both shafts have the same shear stress
Output the water surface pro le plots with all 3 discharges, including the water surface, energy grade line, and critical depth line. Hint: You only need to de ne 3 cross-sections (1 upstream one at the slope break, and 1 at the downstream locatio..
Are installed together? Show calculations to justify your answer and sketch a specific energydiagram to illustrate the process of changes in flow depth in eachcase.
Determine the quantity of lime and soda ash required to soften 1 mgd of the following water. Plan to achieve a hardness of 40 mg/L as CaCO3. Note that an excess of 35 mg/L of lime (CaO) is required to achieve 40 mg/L as CaCO3.
The temperature in the stack is 350 degrees F and the pressure is 725 mm Hg. If the total flow rate of gas out of the stack is 200 standard cubic meters per second, calculate the total mass emissions of particulates out of the stack in kg/day.
For a beam made of 2 materials with different moduli of elasticity,show that the shear stress formula τ =VQ/lt remains validprovided that both Q and I
