1. The products of combustion of a jet engine leave the engine with a velocity relative to the plane of 500 m/s, a temperature of 525?C, and a pressure of 75 kPa. Assuming that k = 1.32, Cp = 1.15 kJ/kg K for the products, determine the stagnation pressure and temperature of the products relative to the airplane.
2. Steam is flowing to a nozzle with a pressure of 400 kPa. The stagnation pressure and temperature are measured to be 600 kPa and 350?C. What are the flow velocity and temperature?
10 kPa of pressure required to push a 3 in^2 piston 5 mm into the compacted soil. Compute the CBR (%) if the same 3 in^2 piston required 100 kPa to penetrate 5 mm in calibrated rock soil.
A water pipeline system is made up of three links in parallel. In any given year, on average, 99 in 100 pumps do not fail. The conditions in the links are statistically independent of each other.
the opponents of globalization focus their criticism on the role of globalization in homogenizing the world and driving
For the following waste and river characteristics just upstream from the outfall, find the minimum downstream DO that could be expected:
Set up the stiffness matrix and determine the value of W in terms of the Euler load at which elastic instability occurs in the symmetrical rigid frame shown in Figure S11.5 . All the members are of uniform section.
A combined pitot static tube has a coefficient of 0.98. Thedifferential head reading is 0.874m of water when it is positionedon the centreline of a pipe of constant diameter.
Enlist the engineering benefits of using concrete for structures.
The 25mm thick strut shown below is glued to the horizontal member along surface AB. The glue can resist a shear stress of 600 kPa before failing, and the horizontal member can resist a normal stress of 2000 kPa before a bearing failure occurs.
Write a balanced net equation for the reaction of the hydrogen ascorbate anion with water where hydrogen ascorbate acts as an acid.
explain the principles of sealant joint design. List several sealant materials suitable for use in the joints that you have shown
A 230,000-lb space shuttle orbiter touches down at about 220 miles per hour (mph). At 200 mph, its drag parachute is deploys. The wheel brakes are applied at 100 mph until wheel sotp and the drag parachute is jettisoned from the orbiter at 35 mph.
A bag of potatoes is sitting on the chair. The force exerted by the potatoes on the frame at one side of the chair is equivalent to horizontal and vertical forces of 24 N and 84 N, respectively, at E and a force of 28 N perpendicular to member BH ..
