You are designing a highway bridge. In particular you aretrying to determine how to put the road surface on the bridge. Youlive in an area where the maximum summertime temperature is 40degrees centigrade and the minimum winter temperature is -30degrees centigrade. The coefficient of linear expansion,α, measures the fractional change in length per unit change intemperature (fractional change = change in length per unit length).A coefficient of linear expansion will be no larger than 0.0001.Consider a section of road surface with length L1 (or L2) attemperature T. If the temperature T increases by?T the length of the section of road surface withL1=3 will increase by 3?L to L1+3?L. If the temperature decreases by?T a section of road surface with length L2=5will decrease in length by 5?L toL2-5?L. The amount the length changes(per unit length of road surface L=1) by is ?L= ?Tα . You are to write a program to determine two things, the maximum size of the space between road sections and theamount of space to leave between the sections of road surface onthe day they are installed. At the maximum temperature there should be no space between the sections of road surface. You must leave enough room between sections of road surface for the road surface to expand to the length it would haveat the maximum temperature of 40 degrees. The user will provide the temperature on the day the installation takes place, the length of each section of road surface to be installed (at the temperature when the installation occurs) and the coefficient of linear expansion of the material being used in the road surface.
The wheel of radius r rolls without slipping and has an angular velocity w. Write an expression for the velocity of point A in terms of theta and show that the velocities of A and B are perpendicular to one another
A 600 MW power plant has an efficiency of 36 percent with 15 percent of the waste heat being released to the atmosphere as stack heat and the other 85 percent taken away in the cooling water.
In a hydrometer test, the data recorded at 60 minutes after the start of the test are as follows: Gs = 2.6, temperature of water T = 24°C and L = 9.2 cm. What is the diameter D of the smallest-sized particles
it has been calculated that the maximum density for the soil will be obtained when the water content reaches 21.5%. Compute how many grams of water must be added to each 1000g of soil( in its natural state) in order to increase the water content 2..
A smooth nozzle with a tip diameter of 2 inches terminates a 6 in waterline. Calculate the mean velocity of efflux from the nozzle when the velocity in the line is 10 ft/s.
a new coal-fired power plant burns 50,000 tons/day of coal with 7% ash and a heating value of 12000 Btu/lbm. Forty percent of the ash drops out of the furnace as slag. Calculate the efficiency rquired of an ESP to remove fly ash
A piston-cylinder assembly containing 1/4 kg of a gas undergoes a constant pressure process at 5 bar beginning with a specific volume of 20 m^3/kg. for the gas in the system the work is -15 kj. determine the final volume of the gas in m^3
Lab studies have shown that the rate constant associated with the process are as follows: k = 0.95 mg COD/mg VSS-day; Y = 0.48 mg VSS/ mg COD, half-saturation K = 85 mg COD/L; ke = 0.07 d-1.
Drawdown at an observation well 15m from the pumped well is 3.0 m and a drawdown at a second observation well 150 m away is 0.30 m. Find the hydraulic conductivity of the aquifer.
The top of the object is 1 m below the surface of the fluid. What are the magnitude and direction of the hydrostatic force acting on the top of the object.
In the Civil War there were numerous incidents in which the bullet fired from a Union soldier's rifle struck and fused with the bullet from a Confederate's rifle. Assume the impact scenario.
Demand for a particular product is normally distributed with a mean of 100 units and a standard deviation of 20 per period. if there are 120 units in inventory at the beginning of this period
