A passenger car being driven on a flat and straight section of a highway at a speed of 65 mph reaches a curved section of the highway with a grade of 5% and a radius of 1,500ft.
Determine:(a) The additional force that will be required to maintain the original speed at 65mph(b) The percentage increase in the total force to maintain the original speed at 65mph
The operating cost will be $10,000 per quarter with a salvage value of $25,000 after its 2-year life. Process B will have a first cost of $250,000, an operating cost of $15,000 per quarter and a $40,000 salvage value after its 4-year life.
What is the concentration of tracer in the reactor 1 h after tracer addition is terminated? The reactor had an initial concentration of tracer of 1.0 mg/L when tracer addition commenced.
Show how Kh, and Kow can be used to describe Koa. You must show how the concentration units for all equilibrium distribution ratios either cancel or remain to give the final value for Koa. Octonal-air partitioning coefficient (Koa = C(octanol)/C(a..
calculate the ratio of area to volume for unit cube a unit sphere in inscribed inside the cube, and as write cylinder inscribed inside the cube.
The landing gear of an airplane can be idealized as the spring-mass damper system. If the runway surface is described y(t)=y0 cos wt, determine the values of k and c that limit the amplitude of vibration of the airplane (x) to 0.1m. Assume m=2000k..
A 175 Mi^2 watershed has a 4200 acre reservior within its boundary . The annual watershed runoff to the reservior is 13in. A flow of 120 mgd (368 ac-ft/day) is to be drafted from the reservior. The annual rainfall is 38in.
The belt starts from rest at time t=0 and its speed increases at a constant rate of 150mm/s^2. Knowing that the coefficient of static friction between the pacakges..
A jet aircraft is flying in a standard atmosphere at an altitude of 4,000 m at 900 km/hr. The frontal intake area of the jet engine is 0.80 m2. The engine exhaust area is 0.56 m2. The temperature of the exhaust gas is 120°C.
Two m^3 of xenon(Xe) are contained in a closed rigid tank at 70 degree C and 2 bar. The tank is heated to a pressure of 10 bar. Assuming that Xe behaves like an ideal gas with a specific heat ration of 1.7
Fabco, Inc., is considering purchasing flow valves that will reduce annual operating costs by $10,000 per year for the next 12 years. Fabco's MARR is 7 percent/year. Using an internal rate of return approach
If an aerial photograph is taken with this camera tilted angleA=35° at an altitude 5000ft., calculate for the ground distance of the angular coverage 60°.
A flat-belt idler pulley is molded from polystyrene with a bronze bushing. Knowing that the densities of polystyrene and bronze are 640 kg/m3 and 9100 kg/m 3, respectively, determine the x coordinate of the center of gravity of the pulley.
