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.
suppose helen deposits $4000 today and one year from today she deposits $1000. Each year she increases her deposit by $500 until she makes her last deposits on roberta's 18 birthday. how much is on deposit after the 18th birhday
Two particles have a mass of 8 Kg and 12 Kg respectively. if they are 800 mm apart, determine the force of gravity acting between them. Compare this result with the weight of each particle.
A direct shear test is performed on a saturated specimen of loose sand. A normal stress equal to 100 kPa is applied and a maximum shear stress of 75 kPa is measured in the shear test. Determine the principal stresses and the orientation of these p..
1. A block of moist soil weighs 12.72 lbs, is 0.1050 ft3 in volume, has a water content of 9.5%, and has a specific gravity of soil solids of 2.7. Assess: Va, Vw, Vs, S, e, gama d. 2. The moist unit weight of a soil is 18.7 kN/m3 Given that Gs=2.71..
an ideal regenerative rankine cycle operates so the steam enters the turbine at 40 bars and 500c and exhausts at 0.1 bar steam at 7 bars is extracted and is used in a single open feed-water heater
ship A leaves port sailing in a direction 60 degree C north of due east and sails for 12 hours at 10 knot . Sheep B leaves the same port 3 hours later and sails due east at 25 knot for 9 hours.
In using the Darcy-Weisbach equation for flow in a pressure conduit, what percentage error is introduced in Q when f is misjudged by 20 percent?
The four approach volumes per day at this intersection are 28,648, 23,856, 12,150, and 10,174. The crash totals for the last 3 years are 91, 96, and 87. What is the annual crash rate for this intersection
Calculate the required compressive strength for a concrete mix design if F'c = 5000 psi and data indicate a standard deviation of 600 psi based on 15 tests for a similar concrete mix
Argon gas is heated in a constant pressure process from 20.0 to 500.°C. Assuming ideal gas behavior, determine: a. The ratio of the final to initial volumes. b. The change in specific internal energy. c. The change in specific enthalpy of the argon.
A steel flat bar of dimensions 4x1x12 inches is PINNED between two copper bars of dimensions 4x2x12 inches at room temp. The PINNED assembly is then cooled by 200 degrees fahrenheit.
