1. The pump in the boat shown pumps 6 ft3 /s of water through a submerged water passage, which has an area of 0.25 ft2 at the bow of the boat and 0.15 ft2 at the stern. Determine the tension in the restraining rope, assuming that the inlet and exit pressures are equal.
2. Oil (sp. gr. = 0.8) flows smoothly through the circular reducing section shown at 3 ft3 /s. If the entering and leaving velocity profiles are uniform, estimate the force which must be applied to the reducer to hold it in place.
The maximum normal stress in the beam. Is this stress comprehensive or tensile? b. The radius of curvature of the beam.
Are the following detectors mass or concentration sensitive?
If the density of the water is 62.4 lb/ft3, what is the mass of water stored in the tower, in lb, when the tank is full? What is the weight, in lbf, of the water if the local acceleration of gravity is 32.1 ft/s2?
calculate the thermal efficiency of the plant.
the velocity of a particle is given by v16t2i 4t3j 5t 2k ms where t is in seconds. if the particle is at the origin
develop the maxwell and kelvin-voigt relations. creep is deformation under constant stress while stress relaxation is
Steam enters the condenser (heat exchanger) of a steam power plant at 20kPa and a quality of 95% with a mass flow rate of 20,000kg/h. A nearby river is used as a source of cooling water where the water will circulate through the tubes within the cond..
a smaller power plant produces steam at 3 mpa 600 c in the boiler. it keeps the condenser at 45 c by transfer of 10 mw
The GE J-79 turbo jet produces a thrust of 10,000lbs at sea level. The inlet diameter is 3.19 ft. If an airplane equipped with the J79 is flying at standard sea level with a velocity of 1,000 ft/sec, estimate the jet velocity relative to the airplane..
How is a modern passenger aircraft brought to halt after landing? Considering the enormity of a modern jetliner and the momentum involved.
Using the results of Problem 17.13, compute the corrosion penetration rate, in mpy, for the corrosion of iron in HCl (to form Fe2 + ions) if the corrosion current density is 8 X 10-5 A/cm2.
The objective of this project is to identify a commercially available heat pump system that will meet annual heating and cooling needs of an existing dwelling in a locale of your choice.
