Same as the book problem but different values.
A suction device is being designed based on the venturi principle to lift objucts submerged in water. The operating water temperature is 50 C. The suction cup is located 1.3 m below the water surface, and the venturi throat is located 1 m above the the water. The atmospheric pressure is 100 kPa. The ratio of the throat area (i.e., the constricted area) to the exit area is 1/4, and the exit area is 0.001 m squared. The area of the suction cup is 0.25 m squared.
a. Find the velocity of the water at the exit for maximum lift condition.
b. Find the volume discharge through the system for maximum lift condition.
c. Find the maximum load the suction cup can support.
State explicitly the restriction that constrains the maximum lift (or minimum pressure in the system).
A 2-lb sphere A is moving to the left with a velocity of 40 ft/swhen it strikes the inclined surface of a 5-lb block B which is atrest. The block is supported by rollers and is attached to a springof constant k=12 lb/in.
Make a sketch indicating the incorrect and correct positions of such an original section corner and also the positions of the adjacent corners used in relocating that corner
The dry density of a compacted sand is 1.87 Mg/m^3 and the density of the solids is 2.67 Mg/m^3. What is the water content of the material when saturated. Include a phase diagram.
a 6 inch soil cement base and an 8 inch crushed stone subbase, which truck will cause more pavement damage?(assume drainage coefficients are 1.0)
The train passes point A with a speed of 30 m/s and begins to decrease its speed at a constant rate of at = - 0.25 m/s2. Determine the magnitude of the acceleration of the train when it reaches point B, where sAB = 412 m.
An in-compressible fluid flows horizontally in the x-y plane with a velocity given by u = 33 (y/h)^1/2 , where y and h are in meters and h is a constant. Determine the average velocity for the portion of the flow between y = 0 and y =h.
a bearing wall carries a dead load of 120kn/m and live load of 100 kn/m. It is to be supported on a 400mm deep continuous footing underlain by a medium sand (unit weight = 19.2 kn/m3, phi= 37 deg, effective c = 0).
If the time required to pay for parking is exponentially distributed with a mean of 15 seconds, find the average time in system.
The pedestal supports a load P at its center. If the material has a mass density p, determine the radial dimension r as a function of z so that the average normal stress in the pedestal remains constant.
An electronic device is available that will reduce year'slabor cost by $10,000. the equipment is expected to last for eightyears. If labor is cost increase at an average rate of 7% per yearand the interest rate is 12% per year
Locate the centroid y of the cross-sectional area for the angle. Set a = 9in ., b = 27in . Find the moment of inertia I_{x'} about the x' centroidal axis.
The total number of effective exposures per unit of advertising medium depends on the region reached. In Louisiana, the number of effective exposures is 70,000, 100,000 and 75,000 for television, radio and direct mail, respectively.
