1.Air at 90 psia and 70 degrees F flows through a 4.5 inch diameter welded steel pipe (e = 0.00015) at 60 lb/min. Find the friction head loss and pressure drop in 200 ft of this pipe. Assume the air to be of constant density.
2.Determine the tensile stress developed in member AB due to a load of P=500# at D. The member AB is 1/2" thick and 2" wide.
3.In the design of a simply supported skew bridge, which direction of reinforcement should be provided? explain with the help of diagram
The program should use both the maximum shearing-strength criterion and the maximum-distortion-energy criterion. It should also print the values of the principal stresses and, if the material does not yield, calculate the factor of safety.
Assume the components act independently and that they are equivalent in the sense that all 3 of them have an 85% success rate. Consider the random variable X as the number of components out of 3 that fail.
A water treatment llant and the water treatment plant removes calcium hardness (Ca2+) by precipitating (making) CaCO3(s). If, after establishing equilibrium with CaCO3(s), the dissolved Ca2+ concentration is 10 mg/L and the pH is 10.5.
The frame is supported in part by normal and friction forces between the wall and the plate at A. Determine the friction force exerted on the plate at A. Also determine the minimum required coefficient of friction at A for the frame to remain in e..
The installation of a radon abatement device is recommended in any home where the mean radon concentration is 4.0 picocuries per liter (pCi/L) or more, because it is thought that longterm exposure to sufficiently high doses of radon can increase t..
At a certain location on the surface of an engineering component, the material is in a state of plane stress with principal stresses of fmax = 150 MPa and fmin = 50 MPa (both tensile). If the yield strength of the material is Y = 350 MPa
a town is installing a new 10 main to carry drinking water. the onlynbspsection remaining to be installed is a segment
The temperature of the poker at the third points of the poker using three elements of equal length. Use the finite element method. You may use Mathcad to solve this problem. If you do, please show all work and add comments to the Mathcad solution ..
Cylindrical, steel bar stock (density = 7833 kg/m3, Cp = 0.465 kJ/(kg C)) of 10-cm diameter is heat-treated by drawing it at a velocity of 3 m/min through a 6-m-long furnace maintained at 900C.
A simply supported beam, 2 inches wide by 4 inches high and 12 feetlong is subjected to a concentrated load of 2000 lb at a point 3 ftfrom one of the supports. Determine the maximum fiber stress and the stress in a fiber located 0.5 inches from the t..
Ammonia is a gas whose smell we detect in manure, cleaning products, and other things. The concentration of this noxious gas can be controlled by regulating the pH of the water because only the non-protonated form, NH3, is volatile.
Mike and Susan hope to retire a few years early, they decided to pay closer attention to the predicted amount of retirement benefits and do some analyses on the numbers.
