1.Carbon dioxide flows in a 2-in by 3-in duct at a pressure of 46 psi and a temperature of 80 degrees Fahreneit. If the atmospheric pressure is 13.8 psia and the flow velocity is 10 fps, calculate the weight flow rate.
2.The velocity of a liquid (s=1.26) in a 3-in pipeline is 2.4 fps. Calculate the rate of flow in cfs, gal/min, slugs/sec, and lb/sec.
3.A sound wave is observed to travel through a liquid with a speed of 1500 m/s. The specific gravity of the liquid is 1.5. Determine the bulk modulus of elasticity, Ev, for this fluid.
4.Name the three factors that influence the degree to which martensite is formed throughout the cross section of a steel specimen. For each, tell how the extent of martensite formation may be increased.
A simply supported steel beam over a 24-ft span carries a uniformly distributed dead load of 2 k/ft, including an allowance for the self-weight, and a live load of 3.5 k/ft. The steel is A992, Grade 50.
A quality characteristic is monitored by a control chart designed so the probability that a certain out-of-control condition will be detected on the first sample following the shift to that state is 1-beta.
The system shown consists of a member which is built in to rigidfoundations at both ends. It is unstrained in the horizontalposition. But then it is put in an upright position, and hence issubject to gravity. Find the stress and strain as a function ..
Calculations with steam mixed with additional steam at a different pressure, A steam press at 650Kpa + dryness fraction of 0.9% flows along a pipe at a rate of 3.5Kg per second
Determine the runoff hydrograph that would be generated by a design 3-hr storm that generates excess rainfall at a constant rate of 10 mm/hr. assume baseflow is constant at 1.0 m3/s.
What is the ratio of the magnitude of E2 to the magnitude of E1? You may neglect the effects of gravity on the proton.
If 5 mg of NaOCl are added to one liter of water and the pH is measured to be 7.8, what is the concentration of hypochlorite ion (OCl-) in mg/L
a certain pesticide is fatal to fish fingerlings at a level of 0.5 parts per million in water. a leaking metal can
A trapezoidal channel has a bed width of 3.5 m and a side slope of 30 degrees from the horizontal. Determine the critical depth and the critical velocity for a flow of 22 cubic meters per second.
A plate storage system for a self-serve salad bar in a restaurant. As plates are added to or withdrawn from the stack, the spring force and stiffness are such that the plates always protrude above the tabletop by about 60 mm.
A ladder of mass 20 lbs. is leaned at an angle of 62 degrees against a smooth frictionless wall. What is the magnitude of the reaction (in lb-wt) where the ladder touches the wall?
Design a square column footing for a 18-in square tied interior column that supports a dead load D= 220 k and a live load L=180 k. The column isreinforced with eight bars, the base of the footing is 4 ft below grade
